Patch for DBD-Pg-0.69..

Hi everyone.

I have made a patch to DBD-Pg-0.69 so that queries that contain the
casing operator "::" work with DBD::Pg v0.69.  Without this patch, any
query with teh casting operator in it will not run.  I could not wait
for a fix from the author for this, so I made the change myself.
Anyways, in case anyone else is strugling with this, the following patch
made against DBD-Pg-0.69 seems to do the trick for me.

Thought I would post this up in case anyone else would like to try it.

Mike
