v0.4.0

The connector Docker image is:

ghcr.io/hasura/ndc-postgres:v0.4.0

Changelog

Added

• There is now a CLI plugin for the Hasura v3 CLI, which allows the CLI to
  automatically introspect the database on demand.
  (#307 and
  #312)
• Support for explaining mutations via the /mutation/explain endpoint.
  (#283)
• Support filtering using in by columns and variables.
  (#283)

Changed

• We have upgraded to ndc-spec v0.1.0, which demands a few changes:
  • The equal and in operators are now understood by the spec, and are
    integrated accordingly.
    (#304)
  • Procedures, which previously had a built-in response structure in ndc-spec,
    now return a nested field structure instead.
    (#296)
• Version 1 and 2 of the configuration and NDC metadata have been deprecated
  and removed.
• Configuration is now a file, configuration.json, in the specified
  configuration directory. It is now version 3, but little has changed from
  version 2. This brings ndc-postgres in line with the connector specification.
  (#305)
• When configuration is initialized, it is expected that the connection URI will
  now be specified using an environment variable, instead of written directly.
  This can be overridden.
  (#325)
• The default port was changed from 8100 to 8080. This is configurable with
  the HASURA_CONNECTOR_PORT environment variable.
• Types and procedures are only supported in unqualified schemas, specified in
  unqualifiedSchemasForTypesAndProcedures.
  (#271)
• The configuration server has been removed in favor of a cli interface.
  (#307 and
  #312)

Fixed

• Fix queries including an IN operator on an empty list.
  (#309)

v0.3.0

[0.3.0] - 2023-01-31

Added

• Basic support for auto-generated insert procedures for tables.
  (#261)
• Support for composite types in inputs and outputs. Right now, no operators are
  provided for composite types, and there is no automatic introspection.
  (#240)
• Support for composite types and arrays in variables.
  (#249)
  (#263)
• When explaining a query without variables (such as when joining across a
  remote relationship), explaining now still provides the generated SQL, and
  omits the EXPLAIN result from PostgreSQL.
  (#241)

Changed

• Native query mutations are now marked as procedures instead of collections
  (#234)
• Introspection now avoids DISTINCT ON to be more compatible with PostgreSQL
  variants
  (#260)
• Invalid request, constraint not met, and unprocessable content errors are
  emitted at the relevant scenarios
  (#239)
