Subject: pgsql: Check for CREATE privilege on the schema in CREATE STATISTICS.
Date: Mon, 10 Nov 2025 15:01:06 +0000
Message-ID: <E1vITOE-005vvJ-0J@gemulon.postgresql.org> (raw)
Check for CREATE privilege on the schema in CREATE STATISTICS.
This omission allowed table owners to create statistics in any
schema, potentially leading to unexpected naming conflicts. For
ALTER TABLE commands that require re-creating statistics objects,
skip this check in case the user has since lost CREATE on the
schema. The addition of a second parameter to CreateStatistics()
breaks ABI compatibility, but we are unaware of any impacted
third-party code.
