v0.83

Sources and sinks

• Improve status reporting for PostgreSQL sources by ensuring definite errors (e.g. dropping a publication upstream) are exposed.

Bug fixes and other improvements

• Prevent users from creating indexes on system catalog objects. If you're using these objects in a context that requires indexing, we recommend creating a view over the catalog objects, and indexing that view instead.

  CREATE VIEW mz_objects_indexed AS
  SELECT  o.id AS object_id,
        s.name AS schema_name
  FROM mz_objects o
  LEFT JOIN mz_schemas s ON o.schema_id = s.id;
  
  CREATE INDEX cara_tmp_i on mz_objects_indexed (object_id);
  

• Fix a bug that allowed users to configure clusters containing storage objects (i.e., sources, sinks) with more than one replica. This is an unsupported state, since such clusters can, at most, have REPLICATION FACTOR = 1.
