ext/pdo_pgsql: drop unneeded code

This check was added in 0db373883fb073e1773823b236daaf0d3f5a0491 and
greps for a private implementation detail of the postgres headers,
removed in https://github.com/postgres/postgres/commit/3c4768d0d17d4569f2417aa5741e0317404b6c45

It hasn't worked as intended for 12 years, and can safely be assumed to
not be needed.
