[pgpool-committers: 2723] pgpool: Fix bugs with data modifying WITH clause reported in bug#153.

[Tatsuo Ishii]

Fix bugs with data modifying WITH clause reported in bug#153.

pgpool-II does not recognize the data modifying WITH clause despite
pgpool-II 3.3 or after has SQL parser which recognizes it. The bug has
been fixed in pgpool-II 3.5 (having PostgreSQL 9.5 parser).

Data modifying WITH clause was introduced in PostgreSQL 9.1. Since
pgpool-II 3.3 has 9.2 parser and pgpool-II 3.4 has 9.4 parser, the fix
is back ported to pgpool-II 3.3 and 3.4.
