What's new

  • We continued to improve the Postgres wire compatibility with more clients and ORMs:
    • Improved the extended wire protocol by supporting flows not starting with a Sync message.
    • Added support for the DEALLOCATE statement.
    • Added support for current_user, current_role, session_user, and user functions.
    • Added support for GREATEST and LEAST functions.
    • Correctly handle CommandComplete and EmptyQueryResponse messages in the Postgres wire protocol. This fixes a bug where the client would hang in particular situations.
    • Added support for information_schema._pg_expandarray over the Postgres wire protocol.
    • Clarified error message on failed internal authentication.
  • We also continued to improve Dedicated Clusters, currently in private alpha:
    • It's now possible to enable extensions (CREATE EXTENSION).
    • Backend support for self-service cluster termination, frontend coming soon.
    • Email notifications for cluster events.
  • The admin UI also got a nice set of improvements:
    • Add support default, unique, and not null constraints on all column types in the UI schema editor.
    • Nicer "branch not found" error page.
    • Copy button in the Edit record dialog for the disabled fields.
    • Fixed last calendar month view in the Usage page.
    • Fixed email column type validation to match the backend.
    • Fixed bug when editing columns of type "multiple".
    • Fixed error when filtering by a File column being NULL.
    • Fixed scrolling issues on workspace pages.
  • The xata schema edit CLI command now works with Postgres wire protocol enabled branches.

What's new in pgroll

  • #341 Allow rename-only alter column operations on unbackfillable columns. Rename operations don't require backfills so there is no reason to impose such a restriction.
  • #344 Add a set comment sub-operation to alter column. The intention is that this can be combined with a change type sub-operation if there is some column metadata that should be updated as part of the type change.
  • #345 Support setting table and column comments to NULL. Without this change it was impossible to remove a comment from a column using the set comment sub-operation
  • #346 Add a set default sub-operation to alter column.

What's new in pgzx

  • #46 Several improvements to the pgzx.mem module, including fixes and tests.
  • #47 Updated the Zig toolchain and the docker images.
