Getting the value for a header GUC on PostgreSQL v14 is done using `current_setting('request.headers')::json->>'name-of-header'` and in a similar way for `request.cookies` and `request.jwt.claims`
PostgreSQL versions below 14 can opt in to the new JSON GUCs by setting the `db-use-legacy-gucs` config option to false (true by default)
This is enabled by adding `!inner` to the embedded resource
/projects?select=*,clients!inner(*)&clients.id=eq.12
This behaviour can be enabled by default with the config option
db-embed-default-join='inner'
Which saves the need for specifying `!inner` on every request.
If this is enabled, the previous behavior can be restored
per request by specifying `!left` on the embedded resource.
/projects?select=*,clients!left(*)&clients.id=eq.12`
Tested on M20/02M/M2M relationships, views, RPC.
* Run CI only on pull requests, push to main and push
to tags matching v*. This avoids running the CI more than
once for a single user action
* Change pre-releases, which are now identified by a version
number with 4 components (e.g., 1.1.1.1)
* Change how release artifacts are packaged, ensuring they
are executable and compressed with xz
Update the hasql-transaction library to version 1.0.1
Add hints and kill thread at configuration read when using incompatible pooling modes: statement pooling and transaction pooling with prepared statements enabled.
* openapi-mode="follow-acl"(default): follows access control for the
JWT role.
* openapi-mode="ignore-acl": ignores access control for the JWT role.
* openapi-mode="disabled": disables OpenAPI output, the root endpoint
replies with 404 Not Found.
Now that PgVersion is not part of DbStructure, Config is a more apt
module for it.
Also rename getDbStructure to queryDbStructure. AppState also had a
getDbStructure function for a record field.
* Use ExceptT to avoid 'staircasing' case analysis in App.hs
* Split large function in App.hs into individual handler functions
* Adapt API of Auth.hs, OpenApi.hs etc. to simplify the use of those modules in App.hs
* Split optional rollback functionality into Middleware
* Unify SimpleError and ApiRequestError into one Error type, so it can be used across modules
Change callProc/createWriteStatement to H.Snippet.
Parametrize the inputs on the same SQLFragments by taking advantage
of hasql-dynamic-statements. It's not necessary to parametrize
every input, inlining with pgFmtLit can still be used for queries
that can't be parametrized(like SET LOCALs).
Also adds hasql-dynamic-statements to Nix and stack.
Specifically, allow point-updates to hasql-notifications, and
give a reasonable lower bound for network (the version that comess
with GHC 8.0 on stackage).
* remove configQuiet from Config
configQuiet was not an end user setting.
The logging setup is now an internal parameter.
* move proxy uri validation to Private dir
Fixes https://github.com/PostgREST/postgrest/issues/1512
Helps on environments where you can't send unix signals(Windows, managed
containers). Also provides better UX for schema reloads - NOTIFY
can be sent from pg clients(psql, pgadmin).
`NOTIFY pgrst` - with no payload - should be done to reload the schema cache.
Notifications with a payload will be ignored.
The channel can be enabled with `db-channel-enabled`(false by default)
and its name can be configured with `db-channel`.
The LISTEN thread uses a dedicated pg connection.
This connection is recovered if it fails.
A debounce of 1ms is done in case too many NOTIFYs arrive.
When doing:
```
cabal upload dist-newstyle/sdist/postgrest-7.0.1.tar.gz
```
The following error is shown:
```
Error: Invalid package
'ghc-options: -Wall -Werror' makes the package very easy to break with
future GHC versions because new GHC versions often add new warnings.
Use just 'ghc-options: -Wall' instead. Alternatively, if you want to
use this, make it conditional based on a Cabal configuration flag
(with 'manual: True' and 'default: False') and enable that flag
during development.
```
Put -Werror in a cabal flag to work around this restriction.
