Materialize v0.65

v0.65.0

Breaking change. Limit the length of object identifiers to 255 bytes.
Include the name and size of cluster replicas in the output of SHOW CLUSTERS as a new column named replicas.
Improve and extend the base implementation of Role-based access control (RBAC):
- Add the SHOW ROLES command, which lists the roles available in the system.
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.
Add mz_internal.mz_object_fully_qualified_names and mz_internal.mz_object_lifetimes to the system catalog. These views enrich mz_objects with namespace and lifetime event information, respectively.
Add mz_internal.mz_expected_group_size_advice to the system catalog. This view provides advice on opportunities to set the EXPECTED GROUP SIZE query hint.

Breaking change. Disallow executing functions from the mz_internal schema (#20998). This change should have no user impact, but please let us know if you run into any issues.
