If you have many calls to pg_connect() without a host
in the connect string, meaning it defaults to /tmp, instead of
changing them you may inject a PGHOST variable into the Apache
environment with /var/pgsql as the value. This will make it
the default host, so basically everything that was going
implicitly to /tmp will go to /var/pgsql instead.
I think in RedHat the definition should go into /etc/sysconfig/httpd
Generally the environment variables described for libpq here:
https://www.postgresql.org/docs/9.6/static/libpq-envars.html
apply to php's pg_connect() as well, since it's really just
a thin wrapper on top of libpq's PQconnectdb().
