The construction `su postgres -c -- bash -c 'psql …'` didn’t behave the way it reads, and only worked by accident: 1. `-c --` sets the command to `--`. 2. `bash` sets the first argument to `bash`. 3. `-c 'psql …'` replaces the command with `psql …`. Thus, `su` ended up executing `<shell> -c 'psql …' bash`, where `<shell>` is the `postgres` user’s login shell, usually also `bash`, which then executed 'psql …' and ignored the extra `bash`. Unconfuse this construction. Note from tabbott: The old code didn't even work by accident, it was just broken. The right fix is to move the quoting around properly.
