They should be faster ... if the client library is really using
server-side prepared statements, and not trying to fake it. Up till
7.4 came out there wasn't any very useful way to use server-side
prepared statements in a driver, and I think only the very latest
version of DBD::Pg knows anything about it. See this thread for
some recent discussion:
