The Ngpsql driver isn't old. They've released updates to it all through version 8 and 9 so far as I know. We do some .Net work against Postgres and it seems to work for what we're doing.
Indeed, the latest release seems to be less than a month old..... It does seem the project could release news items more frequently though. ;-)
Best Wishes,

Yeah, I agree with you. Sorry for that.
On the good side, we released a new beta last week. :)
