For example the length of datums is never sent as a string. The protocol is quite stable...it hasn't changed since 7.4 and there hasn't really been a big call (some of the quite interesting comments in this thread aside) for it to change IMO. The protocol has a binary or text mode, so that user data can be sent/received in text or binary. Using the binary mode is not stable, which is what I think you were basically saying. Now, (self serving pitch here) if you use libpqtypes, you get all the benefits of binary protocol mode (performance, easy data marshaling) without having to worry about data format changes between versions :-D. merlin -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
