[Pgpool-committers] pgpool - pgpool-II: Allow time stamp rewriting to work with arbitrary

[User T-ishii]

Log Message:
-----------
Allow time stamp rewriting to work with arbitrary expression in default
value of a column. Before we detected anything including now() then
simply replaced it to now(). This will lead to wrong rewriting of
default value. for example, timezone('utc'::text, now()).
Note that, however, this only adopts to simple queries. Extended protocols
(for example Java, PHP PDO) or sql "PREPARE" still remain same.
