Ok. I'll integrate it after you have fixed these things. Maybe I'll also 
add a few other things on the todo list, like SQLSTATE support.

OIDs are another issue: In PG 8.0 they are optional, and in 8.1 they are 
not even created by default anymore, but the pg module is using them a 
lot. Any ideas how to deal with that problem?
