Fixes

  • Enabled to alter the setting blocks.read_only_allow_delete on blob tables to make it possible to drop read-only blob tables.

  • Fixed an issue that could cause queries on sys.snapshots to get stuck and consume a significant amount of resources.

  • Fixed an issue with primary key columns that have a DEFAULT clause. That could lead to queries on the primary key column not matching the row.

  • Fixed an issue with aliased sub-relation outputs when used inside the outer where clause expression, resulting in a planner error. Example: SELECT * FROM (SELECT id, true AS a FROM t1) WHERE a

  • Fixed an issue with table functions parameter binding in SELECT queries without FROM clause. Example: SELECT unnest(?).

  • Fixed an issue with VARCHAR and BIT columns with a length limited used in primary key, generated or default column expression. An ALTER TABLE statement removed the length limit from such columns.
