bump version to 12.2.3

Fixes #3660. Load the config after getting the pg version but before loading the schema.

The regression happened on f09655b.

Also remove schema cache load wrapper and separate db queries in different functions.

+# Contributing to PostgREST
+
+**First:** if you're unsure or afraid of _anything_, just ask or
+submit the issue or pull request anyways. You won't be yelled at
+for giving your best effort. The worst that can happen is that
+you'll be politely asked to change something. We appreciate any
+sort of contributions, and don't want a wall of rules to get in the
+way of that.
+
+However, for those individuals who want a bit more guidance on the
+best way to contribute to the project, read on. This document will
+cover what we're looking for. By addressing all the points we're
+looking for, it raises the chances we can quickly merge or address
+your contributions.
+
+## Issues
+
+For questions on how to use PostgREST, please use
+[GitHub discussions](https://github.com/PostgREST/postgrest/discussions).
+
+### Reporting an Issue
+
+* Make sure you test against the latest [stable release](https://github.com/PostgREST/postgrest/releases/latest)
+  and also against the latest [nightly release](https://github.com/PostgREST/postgrest/releases/tag/nightly).
+  It is possible we already fixed the bug you're experiencing.
+
+* Provide steps to reproduce the issue, including your OS version and
+  the specific database schema that you are using.
+
+* Please include SQL logs for issues involving runtime problems. To obtain logs first
+  [enable logging all statements](http://www.microhowto.info/howto/log_all_queries_to_a_postgresql_server.html),
+  then [find your logs](http://blog.endpoint.com/2014/11/dear-postgresql-where-are-my-logs.html).
+
+* If your database schema has changed while the PostgREST server is running,
+  [send the server a `SIGUSR1` signal](http://postgrest.org/en/latest/admin.html#schema-reloading) or restart it to ensure the schema cache
+  is not stale. This sometimes fixes apparent bugs.
+
+## Code
+
+We have a fully nix-based development environment with many tools for a smooth development workflow available.
+Check the [development docs](https://github.com/PostgREST/postgrest/blob/main/nix/README.md) on how to set it up and use it.
+
+### Haskell Conventions
+
+* All contributions must pass the tests before being merged. When
+  you create a pull request your code will automatically be tested.
+
+* All code must also pass [hlint](http://community.haskell.org/~ndm/hlint/) and [stylish-haskell](https://github.com/jaspervdj/stylish-haskell)
+  with no warnings. This helps enforce a uniform style for all committers. Continuous integration will check this as well on every
+  pull request. There are useful tools in the nix-shell that help with checking this locally. You can run `postgrest-check` to do this manually but
+  we recommend adding it to `.git/hooks/pre-commit` as `nix-shell --run postgrest-check` to automatically check this before doing a commit.
+
+### Running Tests
+
+For instructions on running tests, see the [development docs](https://github.com/PostgREST/postgrest/blob/main/nix/README.md#testing).

-
- - #2052, Dropped support for PostgreSQL 9.6 - @wolfgangwalther
- - #2052, Dropped support for PostgreSQL 10 - @wolfgangwalther
- - #2052, Dropped support for PostgreSQL 11 - @wolfgangwalther
- - #3508, PostgREST now fails to start when `server-port` and `admin-server-port` config options are the same - @develop7
- - #3607, PostgREST now fails to start when the JWT secret is less than 32 characters long - @laurenceisla
- - #3644, Fail schema cache lookup with invalid `db-schemas` or `db-extra-search-path` config - @wolfgangwalther

- - #3598, PostgREST now validates the `kid` parameter of the JWT - @wolfgangwalther
-   + If the JWT contains a ``kid`` parameter, then PostgREST will look for the JSON Web Key in the `jwt-secret`.
-   + If the JWT doesn't contain a `kid`, the behavior should be backwards compatible. PostgREST  will try each key in the `jwt-secret` one by one until it finds one that works.
- - #3697, #3602, Querying non-existent table now returns `PGRST205` error instead of empty json - @taimoorzaeem

-# Contributing to PostgREST
+This repository follows the same contribution guidelines as the main PostgREST repository contribution guidelines:
 
-**First:** if you're unsure or afraid of _anything_, just ask or
+https://github.com/PostgREST/postgrest/blob/main/.github/CONTRIBUTING.md
-submit the issue or pull request anyways. You won't be yelled at
-for giving your best effort. The worst that can happen is that
-you'll be politely asked to change something. We appreciate any
-sort of contributions, and don't want a wall of rules to get in the
-way of that.
-
-However, for those individuals who want a bit more guidance on the
-best way to contribute to the project, read on. This document will
-cover what we're looking for. By addressing all the points we're
-looking for, it raises the chances we can quickly merge or address
-your contributions.
-
-## Issues
-
-For questions on how to use PostgREST, please use
-[GitHub discussions](https://github.com/PostgREST/postgrest/discussions).
-
-### Reporting an Issue
-
-* Make sure you test against the latest [stable release](https://github.com/PostgREST/postgrest/releases/latest)
-  and also against the latest [devel release](https://github.com/PostgREST/postgrest/releases/tag/devel).
-  It is possible we already fixed the bug you're experiencing.
-
-* Provide steps to reproduce the issue, including your OS version and
-  the specific database schema that you are using.
-
-* Please include SQL logs for issues involving runtime problems. To obtain logs first
-  [enable logging all statements](http://www.microhowto.info/howto/log_all_queries_to_a_postgresql_server.html),
-  then [find your logs](http://blog.endpoint.com/2014/11/dear-postgresql-where-are-my-logs.html).
-
-* If your database schema has changed while the PostgREST server is running,
-  [send the server a `SIGUSR1` signal](http://postgrest.org/en/latest/admin.html#schema-reloading) or restart it to ensure the schema cache
-  is not stale. This sometimes fixes apparent bugs.
-
-## Code
-
-We have a fully nix-based development environment with many tools for a smooth development workflow available.
-Check the [development docs](https://github.com/PostgREST/postgrest/blob/main/nix/README.md) on how to set it up and use it.
-
-### Haskell Conventions
-
-* All contributions must pass the tests before being merged. When
-  you create a pull request your code will automatically be tested.
-
-* All code must also pass [hlint](http://community.haskell.org/~ndm/hlint/) and [stylish-haskell](https://github.com/jaspervdj/stylish-haskell)
-  with no warnings. This helps enforce a uniform style for all committers. Continuous integration will check this as well on every
-  pull request. There are useful tools in the nix-shell that help with checking this locally. You can run `postgrest-check` to do this manually but
-  we recommend adding it to `.git/hooks/pre-commit` as `nix-shell --run postgrest-check` to automatically check this before doing a commit.
-
-### Running Tests
-
-For instructions on running tests, see the [development docs](https://github.com/PostgREST/postgrest/blob/main/nix/README.md#testing).

+
+You can use the string representation for `PostGIS <https://postgis.net/>`_ data types such as ``geometry`` or ``geography`` (you need to `install PostGIS <https://postgis.net/documentation/getting_started/>`_ first).
+

+
+  create table coverage (

+  );
+
+To add areas in polygon format, you can use string representation:

+.. code-block:: bash
+
+  curl "http://localhost:3000/coverage" \
+    -X POST -H "Content-Type: application/json" \
+    -d @- << EOF

+
+Now, when you request the information, PostgREST will automatically cast the ``area`` column into a ``Polygon`` geometry type.

-Using string representation
----------------------------
-
-To insert areas in polygon format, you can use string representation:

-.. code-block:: bash
-
-  curl "http://localhost:3000/coverage" \
-    -X POST -H "Content-Type: application/json" \
-    -d @- << EOF

-      { "id": 4, "name": "diamond", "area": "SRID=4326;POLYGON((5 0, 10 5, 5 10, 0 5, 5 0))" }
-    ]
-  EOF
-
-PostgREST will automatically cast the ``area`` column into a ``Polygon`` geometry type.

 Aggregate Functions
 ###################
 
-PostgREST supports the following aggregate functions: ``avg()``, ``count()``, ``max()``, ``min()``, and ``sum()``.
+Aggregate functions allow you to summarize data by performing calculations across groups of rows. For instance, if you have an ``orders`` table that has an ``amount`` column, you could use an aggregate function to get the sum of the ``amount`` column, either for all rows, or for each group of rows that share specific values, for instance all rows that share the same ``order_date``.
-Please refer to the `section on aggregate functions in the PostgreSQL documentation <https://www.postgresql.org/docs/current/functions-aggregate.html>`_ for a detailed explanation of these functions.
 
 .. note::
- Aggregate functions are *disabled* by default in PostgREST, because they can create performance problems without appropriate safeguards.

-  While this is still supported, it may be deprecated in the future, and thus use of this legacy feature is **not recommended**.

-``count()`` is a special case because it can be used with or without an aggregated column. For example:
+
+``count()`` is treated specially, as it can be used without an associated column. Take for example the following query:
 
 .. code-block:: bash
 
-  curl "http://localhost:3000/orders?select=count(),observation_count:observation.count(),order_date"
+  curl "http://localhost:3000/orders?select=count(),order_date"
+
+This would return a row for each unique value in the ``order_date`` column, with the count of all rows that share the same ``order_date``:
 
 .. code-block:: json
 
   [
     {
       "count": 4,
-      "observation_count": 2,

-      "observation_count": 1,
       "order_date": "2023-01-02"
     }
   ]
 
-Note that there is a difference between the result of ``count()`` and ``observation.count()``.
+When ``count()`` is used with an associated column, its behavior is slightly different: It will return the count of all values that are not ``NULL``. This is due to how PostgreSQL itself implements the ``count()`` function.

+Renaming and Casting
+====================
+
+Renaming Aggregates
+-------------------
+
+Just like with other columns, you can rename aggregated columns too. See :ref:`renaming_columns` for details.
+
+Renaming columns is especially helpful in the context of aggregate functions, as by default a column with an aggregate function applied will take on the name of the applied aggregate function. You may want to provide a more semantically meaningful name or prevent collisions when using multiple aggregate functions of the same type.
 
 Casting Aggregates
-==================
+------------------
 
-It is :ref:`possible to cast <casting_columns>` the aggregated column or the aggregate itself, or both at the same time.
+When applying an aggregate function to a column, you are able to cast both the value of the input to the aggregate function *and* the value of the output from the aggregate function. In both cases, the syntax works as described in :ref:`casting_columns`, with the only difference being the placement of the cast.
 
-Casting the Aggregated Column
+Casting the Value of the Input
------------------------------
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
-For example, let's say that ``orders`` has an ``order_details`` :ref:`JSON column <json_columns>` with a ``tax_amount`` key.
+For instance, imagine that the ``orders`` table has a JSON column, ``order_details``, and this column contains a JSON object that has a key, ``tax_amount``. Let's say you want to get the sum of the tax amount for every order. You can use the ``->`` or ``->>`` operators to extract the value with this key (see :ref:`json_columns`), but these operators will return values of the types JSON and ``text`` respectively, and neither of these types can be used with ``sum()``.
-We cannot sum ``tax_amount`` directly because using ``->`` or ``->>`` will return the data in ``json`` or ``text`` format.
+
-So we need to cast it to a compatible type (e.g. ``numeric``) right before the aggregate function:
+Therefore, you will need to first cast the input value to a type that is compatible with ``sum()`` (e.g. ``numeric``). Casting the input value is done in exactly the same way as casting any other value:
 
 .. code-block:: bash
 
   curl "http://localhost:3000/orders?select=order_details->tax_amount::numeric.sum()"
 
+With this, you will receive the sum of the casted ``tax_amount`` value:

-Grouping by an Embedded Resource
+Using Aggregate Functions with Resource Embedding
---------------------------------

-Similar to grouping by columns, aggregate functions can also be grouped by embedded resources.
+Aggregate functions can be used in conjunction with :ref:`resource_embedding`. You can use embedded resources as grouping columns, use aggregate functions within the context of an embedded resource, or use columns from a spreaded resource as grouping columns or as inputs to aggregate functions.

+When you :ref:`spread an embedded resource <spread_embed>`, the columns from the spreaded resource are treated as if they were columns of the top-level resource, both when using them as grouping columns and when applying aggregate functions to them.
-In other words, it will behave as if the aggregate was done in the top-level relationship itself. For example:
+
+Grouping with Columns from a Spreaded Resource
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+For instance, assume you want to sum the ``amount`` column from the ``orders`` table, using the ``city`` and ``state`` columns from the ``customers`` table as grouping columns. To achieve this, you may select these two columns from the ``customers`` table and spread them; they will then be used as grouping columns:
 
 .. code-block:: bash
 
-  curl "http://localhost:3000/orders?select=order_date,...customers(subscription_date.max(),subscription_date.min())
+  curl "http://localhost:3000/orders?select=amount.sum(),...customers(city,state)
 
-This will take the ``max`` and ``min`` subscription date of every customer and group it by the ``order_date`` column:
+The result will be the same as if ``city`` and ``state`` were columns from the ``orders`` table:
+
+.. code-block:: json

+    }
+  ]
+
+Aggregate Functions with Columns from a Spreaded Resource
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Now imagine that the ``customers`` table has a ``joined_date`` column that represents the date that the customer joined. You want to get both the most recent and the oldest ``joined_date`` for customers that placed an order on every distinct order date. This can be expressed as follows:
+
+.. code-block:: bash

+  curl "http://localhost:3000/orders?select=order_date,...customers(joined_date.max(),joined_date.min())
+
+As columns from a spreaded resource are treated as if they were columns from the top-level resource, the ``max()`` and ``min()`` are applied *within* the context of the top-level, rather than within the context of the embedded resource, as in the previous section.

-   Aliasing spreaded columns is recommended since JSON allows duplicate keys. Example:

-      {"id":5,"name":"Orphan","id":null,"name":null}]
-
-   This can be a problem in Javascript objects, since only the last duplicated key will be considered. To solve it do:
-
-   .. code-block:: bash
-
-     curl --get "localhost:3000/projects" \
-       -d "select=id,name,...clients(client_id:id,client_name:name)"

-
-  + If no key has a matching ``kid`` (or if they don't have one defined), the token will be rejected with a :ref:`401 Unauthorized <pgrst301>` error.

 JWT Claims Validation
----------------------
+~~~~~~~~~~~~~~~~~~~~~
 
-Time-Based claims validation
+PostgREST honors the :code:`exp` claim for token expiration, rejecting expired tokens.
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The time-based JWT claims specified in `RFC 7519 <https://datatracker.ietf.org/doc/html/rfc7519#section-4.1.4>`_ are validated:
-
-- ``exp`` Expiration Time
-- ``iat`` Issued At
-- ``nbf`` Not Before

-
-.. _jwt_aud:
-
-``aud`` validation
-~~~~~~~~~~~~~~~~~~
-
-PostgREST has built-in validation of the `JWT audience claim <https://datatracker.ietf.org/doc/html/rfc7519#section-4.1.3>`_.
-It works this way:
-
-- If :ref:`jwt-aud` is not set (the default), PostgREST identifies with all audiences and allows the JWT for any ``aud`` claim.
-- If :ref:`jwt-aud` is set to a specific audience, PostgREST will check if this audience is present in the ``aud`` claim:
-
-  + If the ``aud`` value is a JSON string, it will match it to the :ref:`jwt-aud`.
-  + If the ``aud`` value is a JSON array of strings, it will search every element for a match.
-  + If the match fails or if the ``aud`` value is not a string or array of strings, then the token will be rejected with a :ref:`401 Unauthorized <pgrst303>` error.
-  + If the ``aud`` key **is not present** or if its value is ``null`` or ``[]``, PostgREST will interpret this token as allowed for all audiences and will complete the request.
-
-.. _jwt_caching:
-
-JWT Cache
----------
-
-JWT signature validation (specially :ref:`asym_keys` such as RSA) is slow, we can cache ``JWT`` validation results to avoid this performance overhead.
-
-The JWT cache is bounded and uses the `SIEVE algorithm <https://cachemon.github.io/SIEVE-website>`_ for efficient eviction. The cache is enabled by default and can be configured with :ref:`jwt-cache-max-entries`.
-
-It's recommended to leave the JWT cache enabled as our load tests indicate ~20% more throughput for simple GET requests when using it. This while reducing CPU utilization in exchange for a bit more memory.
-
-:ref:`jwt_cache_metrics` are available.
-
-.. note::
-
-  - If the ``jwt-secret`` is changed and the config is reloaded, the JWT cache will reset.
-  - JWTs that pass :ref:`jwt_signature` are cached, regardless if they pass :ref:`jwt_claims_validation`. We do this to ensure responses stays fast under common failure cases (such as expired JWTs).
-  - You can use the :ref:`server-timing_header` to see the peformance benefit of JWT caching.
-
-.. _jwt_role_extract:
-
-JWT Role Extraction
--------------------
-
-A JSPath DSL that specifies the location of the :code:`role` key in the JWT claims. It's configured by :ref:`jwt-role-claim-key`. This can be used to consume a JWT provided by a third party service like Auth0, Okta, Microsoft Entra or Keycloak.
-
-The DSL follows the `JSONPath <https://goessner.net/articles/JsonPath/>`_ expression grammar with extended string comparison operators. Supported operators are:
-
-- ``==`` selects the first array element that exactly matches the right operand
-- ``!=`` selects the first array element that does not match the right operand
-- ``^==`` selects the first array element that starts with the right operand
-- ``==^`` selects the first array element that ends with the right operand
-- ``*==`` selects the first array element that contains the right operand
-
-Usage examples:
-
-  .. code:: bash
-
-    # {"postgrest":{"roles": ["other", "author"]}}
-    # the DSL accepts characters that are alphanumerical or one of "_$@" as keys
-    jwt-role-claim-key = ".postgrest.roles[1]"
-
-    # {"https://www.example.com/role": { "key": "author" }}
-    # non-alphanumerical characters can go inside quotes(escaped in the config value)
-    jwt-role-claim-key = ".\"https://www.example.com/role\".key"
-
-    # {"postgrest":{"roles": ["other", "author"]}}
-    # `@` represents the current element in the array
-    # all the these match the string "author"
-    jwt-role-claim-key = ".postgrest.roles[?(@ == \"author\")]"
-    jwt-role-claim-key = ".postgrest.roles[?(@ != \"other\")]"
-    jwt-role-claim-key = ".postgrest.roles[?(@ ^== \"aut\")]"
-    jwt-role-claim-key = ".postgrest.roles[?(@ ==^ \"hor\")]"
-    jwt-role-claim-key = ".postgrest.roles[?(@ *== \"utho\")]"
-
-.. note::
-
-  The string comparison operators are implemented as a custom extension to the JSPath and does not strictly follow the `RFC 9535 <https://www.rfc-editor.org/rfc/rfc9535.html>`_.

-===================
-
-For error cases, the standard `Proxy-Status <https://www.rfc-editor.org/rfc/rfc9209.html#name-the-proxy-status-http-field>`_ header is returned with the error code. The error code comes from either :ref:`PostgREST <pgrst_errors>`, :ref:`PostgreSQL <postgresql_errors>` or :ref:`Custom <custom_errors>` errors. This is useful when doing ``HEAD`` requests where the HTTP status is not descriptive enough.
-
-For example, doing a request on a table with high count (say 30_000_000), we get:

-Debouncing
-~~~~~~~~~~
-
-PostgREST does not reload the schema cache for each notification when several ``NOTIFY pgrst`` events are generated quickly after one another.
-
-There are two cases to consider: when notifications are sent within a single transaction and when they are sent across multiple transactions.
-
-In the first case, PostgreSQL deduplicates identical ``NOTIFY`` events within the same transaction. This means that even if multiple ``NOTIFY pgrst`` statements are executed before a ``COMMIT``, only a single notification is delivered to PostgREST.
-
-In the second case, when notifications are sent from separate transactions in a short time span, PostgREST applies a debouncing mechanism to avoid excessive schema cache reloads.
-
-Instead of reloading the schema cache for each notification, events are grouped within a small time window of 100 milliseconds. The reload function is executed once immediately when the first notification is received and once more after the burst of events settles, resulting in at most two executions within that time window.
