Upgrading from 10-9 to 1x-xx fails on DSM devices: DETAIL: Permissions should be u=rwx (0700) or u=rwx,g=rx (0750).

I'm running gitlab on an Synology box running the latest version of DSM (6.2.3-25426 Update 2). Also I've recreated this issue on multiple different boxes of Synology and I'm not sure how to resolve this. I've tried different version of postgresql and the only reason really why I've tried updating is because gitlab requires it with version 13.xx and on.

It stays stuck in this loop:

Any help with this would be appreciated.
Thank you.

No repository file, test, or entry point is identified in the report. Start by reproducing the PostgreSQL 10-to-11 migration on a Synology DSM 6.2.3 device and inspect the upgrade log around initialization of /var/lib/postgresql/11/main. Done means the migration completes without the invalid-permissions failure.
