Is this correct? (According to a few tests, > it is.) Right, it is. libpq4 == libpq3 with a few symbols removed that were not actually intended to be used. I. e. you can use both libraries to connect to servers from 7.3.something to 8.0 (and probably even later versions). However, the idea is to always use the newest version and to fade out the usage of libpq3.
