When Odoo is installed with the latest version of the PostgreSQL client (postgres-client or postgres-client-16) and running in Docker (possibly other environments as well but not reproduced so far), executing `pg_dump` via `exec_pg_command` fails with
Database backup error: Postgres subprocess ('/usr/bin/pg_dump', '--no-owner', '--file=/tmp/tmpmnqiktog/dump.sql', '15TEST') error 1
This seems to be because `os.devnull` is being opened in *read* mode which is incorrect (as it's written to). It's not entirely clear if older `pg_dump` simply ignored the non-writable stdout or if docker adds some restrictions which cause the failure.
Either way this can be solved by either opening `os.devnull` in write mode or switching to the `DEVNULL` constant. While the function is deprecated in 16.0 (7f14631fe8) and removed in master (ae3056f3f4fca82c6aee69bf201532e14829c45e) the latter is not a huge change and it a touch cleaner.
