Do nothing.  The problem you are raising isn't very serious since
RPM-style installations don't support concurrent installation of
multiple PG versions anyway.  That being the case, it doesn't really
matter whether 8.0 psql can use a 7.4 library or vice versa.

To do otherwise would essentially amount to deciding that get_progname
is part of the exported API of libpq forevermore.  That's not something
I'm willing to buy into.  It was a mistake that it was done that way in
7.4, and I want to rectify that mistake before it gets any more
entrenched.
