XML/SOAP support for RPC
RPC now understands the
text/xml media type, allowing SQL functions to send XML output(
Accept: text/xml) and receive XML input(
Content-Type: text/xml). This makes SOAP endpoints possible, check the Create a SOAP endpoint how-to and the Scalar Function Response Format reference for more details.
GeoJSON is supported across the board(reads, writes, RPC) with the
Accept: application/geo+json header, this depends on PostGIS from the versions 3.0.0 and up. The working with PostGIS section has an example to get you started.
The execution plan of a request is now obtainable with the
Accept: application/vnd.pgrst.plan header. The result can be in
json formats and is compatible with EXPLAIN vizualizers like explain.depesz.com or explain.dalibo.com.
Accessing fields of a Composite type or elements of an Array type is now possible with the arrow operators(
->>) in the same way you would access a JSON type fields.
limitcan now affect the number of updated/deleted rows. See Limited Update/Delete.
You can now activate the “Authorize” button in SwaggerUI by enabling the openapi-security-active configuration. Add your JWT token prepending
Bearer to it and you’ll be able to request protected resources.
Two health check endpoints are now exposed in a secondary port.
Logging now shows the database user.
It is now possible to execute PostgREST without specifying any configuration variable. The three that were mandatory on the previous versions, are no longer so.
To increase consistency, all the errors messages are now normalized. The
messagefields will always be present in the body, each one defaulting to a
nullvalue. In the same way, the errors that were raised with
SQLSTATEnow include the
codein the body.
To further clarify the source of an error, we now add a
PGRSTprefix to the error code of all the errors that are PostgREST-specific and don’t come from the database. These errors have unique codes that identify them and are documented in the PostgREST Error Codes section.
Added a Working with PostgreSQL data types how-to, which contains explanations and examples on how to work with different PostgreSQL data types such as timestamps, ranges or PostGIS types, among others.
Added in-database and environment variable settings for each configuration variable.
Added the File Descriptors subsection.
Added a reference page for Errors.
Moved the Casting type to custom JSON how-to to the Casting a Range to a JSON Object subsection.
Removed direct links for PostgREST versions older than 8.0 from the versions menu.
Removed the Embedding table from another schema how-to.
Restructured the Resource Embedding section:
Many-to-many relationships now require that foreign key columns be part of the join table composite key
For migrating to this version, the less invasive method is to use Computed relationships to replace the previous many-to-many relationships.
Otherwise you can change your join table primary key. For example with
alter table permission_user drop constraint permission_user_pkey, add primary key (id, user_id, permission_id);
Views now are not detected when embedding using Target Disambiguation.
limit/offsetnow limits the affected rows on
offsetonly limited the returned rows but not the actual updated rows(#2156)
max-rowsis no longer applied on
This was misleading because the affected rows were not really affected by
max-rows, only the returned rows were limited(#2155)
