To me the principle of least surprise says that it should be fixed. At
this point a pre-9.4 server is putting its socket where the primary
client library(libpq) to said server cannot find it if a 9.4+ server is
installed. The options seem to be:
1) Use the libpq appropriate for each Postgres version.
2) Modify the postgresql.conf to point at the socket directory that the
controlling libpq is looking for. I could see this being messy.
3) Document the change in behavior. Possibly here:

PostgreSQL Yum Repository
