Thanks Albe. I've poked around a bit more with this question, and it seems that the functionality was moved out of the server and into the client. It's no longer possible to have autocommit set to anything other than true. (But in case anyone else is wondering, the query "show autocommit" is what I was looking for, to find out what current status is.) So I guess now I need to check out the PHP bindings, since all my C++ code uses libpqxx and much better handling of transactions. (And I rather doubt that you guys will know what Pike is, much less whether it can automatically open a transaction and not commit it when a query comes in.) I'd really rather get off PHP altogether, but that isn't looking likely at the moment!
