Sure, basically, modern versions of the client library can talk to older versions of the database backend up to a point (i.e. the 7.4 library in beta can go back to 6.5 or 6.4 or something like that. Support for 6.2 or thereabouts was recently dropped.)
However, going the other way, old connect libs and newer postgresql back end versions can result in an issue where the old lib can't connect. the normal solution is to link to / use the newer connection libraries that come with a late model pgsql (7.3, 7.4 etc...)
