ERROR: relation "table_without_models" does not exist

After migration to 19.2.0 I started noticing this error in logs:

gitlab.postgresql  | 2026-07-30 00:37:57.381 UTC [110] ERROR:  relation "table_without_models" does not exist

Start with compose.yml and reproduce the PostgreSQL errors while upgrading to GitLab 19.2.0 and the listed PostgreSQL image. Trace which startup or migration entry point issues SELECT pg_get_serial_sequence for table_without_models, then verify that the error no longer appears and document the compatible configuration or required fix.
