You don't need that, because psycopg uses libpq that can connect to
older versions of the backend.

I don't know about RPMs but in Debian we have multiple versions of
postgresql and only *one* libpqXX package (usually it comes from the
most recent stable release). So my suggestion is to have only one
version of psycopg linked to the most recent libpq package.
