[pgpool-general: 3220] Re: pgpool 3.3.4 + postgresql 9.3.4 : undefined symbol: HeapTupleHeaderGetDatum when creating pgpool_adm ext.

[Tatsuo Ishii]

The extension allows you to use pcp command functionality via
PostgreSQL's function.  You can safely remove them if you don't need
that (you can do exactly same thing by using pcp commands).
