[pgpool-committers: 1970] pgpool: Adopt PostgreSQL 9.4 having to_regclass.

[Tatsuo Ishii]

Adopt PostgreSQL 9.4 having to_regclass.

PostgreSQL 9.4 has built-in function "to_regclass", which has
equivalent functionality of pgpool_regclass. Now pgpool searches
to_regclass first then try pgpool_regclass.
