I'd say just go ahead and send it to the db. Getting a java regex package
to match up *exactly* with pg's seems rather unlikely. Why not just let
pg tell you if it was valid or not? I'm guessing you want to detect regex
errors from other sql errors, but SQLException.getSQLState() should do
that for 7.4+ servers.
