[Pgpool-committers] pgpool - pgpool-II: Add pgpool_regclass function.

[User T-ishii]

Log Message:
-----------
Add pgpool_regclass function. This is an alternative for regclassin.
Problem is, regclassin throws an error if invalid table name is
specified and pgpool's internal query fails.
Someday we might have such a builtin function but until that day
we use pgpool_regclass instead...
