Back over Thanksgiving, I kludged together a proof of concept
'DBD::ChurlPg' that does serverside prepare() for DML statements [among
some other things that I wanted.] I did this for myself, so I was not
going to show it to anyone, but what the heck.

If you are  intersted in taking a look, the code is here:
http://www.remotelinux.com/rlippan/   There is some uglyness in there and 
rows() is broken (it is using default from driver.xst), but otherwise it 
has been working for me for the past few months.

I'd love to get some feedback on the changes that I made.  And if wanted
(read other's will think that the changes are useful), I will clean up the
code and port the changes over to the latest version of DBD::Pg.
