Well, we're calling PQsetNoticeProcessor[1], from inside dbd_db_login,
so I should be able to pass in imp_dbh as the "arg" argument. The bit
that I wasn't sure about before was what to cast it to in order to
retrieve it from a void *.

How will that work? Is that for any sort of asynchronous message from
the database?

It does, I just couldn't figure it out in the 30 minutes I spent looking
at it. I need to go back and spend more time with the docs and less
being lazy. :-)
