Whenever running backups on PostgreSQL databases, they fail with the below error.

PostgreSQL authentication failed - no password supplied. PGPASSWORD environment variable may not be working correctly on this system. Password length: 36, Password empty: false. Consider using a .pgpass file as an alternative. stderr: WARNING: password file "/databasus-data/temp/pgpass_83993aef-e1b1-4c05-bea0-4c38969f8c6a1271491154/.pgpass" has group or world access; permissions should be u=rw (0600) or less pg_dump: error: connection to server at "n8n_postgres" (172.31.0.17), port 5432 failed: fe_sendauth: no password supplied

MariaDB backups still continue to work normally. Reverting the container to anything up to and including v2.21.0 resolves the issue.
