Fix missing arguments when PostgreSQL upgrade times out

This is a small regression from
https://gitlab.com/gitlab-org/omnibus-gitlab/-/merge_requests/7247.
When the PostgreSQL upgrade times out, previously the script
would error out with `wrong number of arguments (given 0, expected 1)
(ArgumentError)`.

Changelog: fixed
