pgsql: Band-aid for regression test expected-results problem with times

Band-aid for regression test expected-results problem with timestamptz.

We probably need to tell the remote server to use specific timezone and
datestyle settings, and maybe other things.  But for now let's just hack
the postgres_fdw regression test to not provoke failures when run in
non-EST5EDT environments.  Per buildfarm.
