Right now listening sockets initialization, management and usage is split between App, AppState and Admin modules: they are created in AppState.init and remembered in AppState but used only in App and Admin.
It has several negative consequences:
- sockets are initialized even if not needed (eg. command line invocations like dump-config or dump-schema)
- it is impossible to start listening on a socket after initial schema cache load because it requires AppState
This change decouples listen socket management from AppState. Sockets are created only when needed (ie. not in command line tools invocation) and passed to admin application and to Warp by the App module.
There is unnecessary coupling between observation messages and emited log entries. This causes schema loading logic to emit redundant events: SchemaCacheSummaryObs and SchemaCacheLoadedObs.
Logically - we want to emit a single event containing both summary and timing information. How it is logged is a different matter and should be decoupled.
This commit
* changes observationMessage function returning Text to observationMessages returning [Text] so that it is possible to return multiple (or zero) messages to log based on an observation event
* Removes SchemaCacheSummaryObs constructor from Observation type and adds summary text to SchemaCacheLoadedObs
Set error verbosity using this config. The verbosity can
be set to `verbose` or `minimal` for client error responses.
This only affects client side HTTP responses, server side logs
are not affected by this config.

Fixes#4646. Using the repro on #4646, this now produces the log:
```
11/Feb/2026:09:40:08 -0500: Warp server error: stack overflow
```
When:
```
$ curl localhost:3000/
curl: (52) Empty reply from server
```
- Move privileges and grants to privileges.sql
- Move schema, tables and functions to schema.sql
- Move global database settings to database.sql

Diagnosing problems with listener channel notifications not being handled properly by PostgREST connected to read replicas is difficult. Issues might be related to lost connections and listener not being connected to the right host after failover or database server restarts.
This patch adds logging of actual host:port used by libpq connection opened by the listener. It should make it easier to find out if PostgREST is connected to the right host.
* Calculation of hint message when requested relation is not present in schema cache requires creation of a FuzzySet (to use fuzzy search to find candidate tables). For schemas with many tables it is costly.
This patch introduces dbTablesFuzzyIndex in SchemaCache to memoize the FuzzySet creation.
* Additionally, because of FuzzySet large memory requirements, this patch introduces a limit of 500 relations per schema, above which FuzzySet is not created and hint calculation disabled.
The hasSingleUnnamedParam function was only checking the parameter type
but not whether the parameter actually had no name. This caused functions
with a single NAMED parameter (e.g., `foo(data json)`) to incorrectly
match the single-param fallback mode.
The result was a confusing PostgreSQL error 42883 "function does not exist"
instead of a clean PGRST202 error explaining that no matching function
was found.
Added ppName == mempty check so functions with named parameters don't
incorrectly match the single-param fallback.
We don't allow accessing schemas "pg_catalog" and "information_schema".
Instead of silently failing requests on these schemas, this now adds
logging an error on startup when these schemas are found in `db-schemas`
config.

The `test_io.py` module is too bloated (2100+ lines). To
logically group related tests, as a first step, this commit
separates authentication related IO tests into `test_auth.py`
module.

Renames these scripts to `postgrest-with-pg-xx`. The renaming
helps reduce the length of temporary filenames. This is needed
to ensure that socket file names remain under the maximum
allowed length of 107 chars.
Closes#4461.

- Adds fixtures to `test/io/fixtures.sql` to test resource
embedding related queries.
- Moves the resource embedding related tests that no longer
require big schema from `test_big_schema.py` to `test_io.py`.
Closes#4417.

The `dumpQi` function is only used in the `Config.hs` module, so
it is moved there. This also adds a doctest for `quoteQi` and
clarifies its usage.

When db-pre-config is accidentally set to a pg reserved word
like "true", it fails with a confusing error. The function
names should be properly quoted to avoid such errors. This commit
resolves this by quoting the pre-config function name.

To make schema cache loading wait tests robust it is necessary to provide three separate internal config variables:
* "internal-schema-cache-query-sleep" - introduces delay in schema queries execution
* "internal-schema-cache-load-sleep" - introduces delay between schema queries execution and processing their results
* "internal-schema-cache-relationship-load-sleep" - introduces delay in processing relationship query results
Thanks to these changes it is now possible to test various schema loading scenarios with the right granularity robustly (eg. make sure requests wait for schema loading but not for relationship loading).
There are a few benefits for this:
- All fixtures in one module, so single source of truth.
- The fixtures are automatically imported and injected by pytest
so no explicit imports needed for these.
- Linters won't complain about redefinition of outer scope objects.

The `--ready` flag is a wrapper around the admin server
`/ready` request. This is done through using an http client

Moves the `set_statement_timeout` and `reset_statement_timeout`
function to postgrest.py. This cleans up test_io.py so it only
contains tests. Also makes these functions reusable in other
other tests like test_cli.py.
