libs, compat and upgrades (oh my) - Mailing list pgsql-admin

To prepare for server upgrades I'm planning to update the clients on a
set of servers from 9.1 to 9.4. The servers are running CentOS 5 i386.

Somewhere between 9.1 and 9.4 the compat-postgresql-libs, which offered
libpq.so.4x, has disappeared from the repository causing dependency
issues on upgrade.

Any recommendations on which of many approaches might be best to address
this?

Cheers,
Steve
