You can't, and you'll get exactly zero community support for trying. We don't believe in embedded databases --- or at least, we don't believe in trying to use Postgres as one. We like a hard-and-fast separation between client and database server, so that client programming mistakes can't corrupt the database. You could possibly do what you are thinking of in the form of user-defined functions executing in the backend, but the communication overhead to the client side is likely more than you want, and you'll be relying on APIs that we consider backend-internal and feel free to whack around at the drop of a hat. I'd suggest looking for something that's actually intended to be an embedded database. sqlite maybe, though I'm no expert on the subject. For that matter, have you looked at good old dbm? regards, tom lane
