Pull Request for Issue #24769 .

Summary of Changes

Fix the schema update changes from PR #20561 for PostgreSQL so they are consistent with a new installation.

Testing Instructions

Drone failure is not related to this PR. Phpcs was successful. It was the prepare step which failed.

@twister65 I noticed you test with PostgreSQL, too. If you have time, could you test my PR here? Thanks in advance if so.

Drone failure again is not related to this PR. Phpcs was successful. This time it was analysis4x which failed.

It’s the tool we use for the security analysis part of drone (which was failing). It’s now passing so I can merge this! Thanks!
