v0.64.0

SQL

• Improve and extend the base implementation of Role-based access control (RBAC):

  • Require specifying a target role in the ALTER DEFAULT PRIVILEGES command. Previously, the target role was optional and defaulted to the current role, which is seldom what users intend to achieve with this command.

  • Add the has_role function as an alias to pg_has_role. This function reports if a specified user has USAGE or MEMBER privileges for a specified role.

It's important to note that role-based access control (RBAC) is disabled by default. You must contact us to enable this feature in your Materialize region.

Bug fixes and other improvements

• Fix a bug that let users specify the DETAILS option when creating a PostgreSQL source {{% gh 20944 %}}.

• Extend support for single DDL statements in explicit transactions to the ALTER and DROP commands. This improves the integration experience with external tools like Deepnote and Hex.
