[pgpool-committers: 9006] pgpool: Fix compiler warning.

[Tatsuo Ishii]

Fix compiler warning.

pgpool-regclass.c needed to include "utils/varlena.h".  Also sort out
the header files order (except postgres.h which needs to be appear at
the top among PostgreSQL header files).

The compiler warning was reported by Florian Weimer.
