This indicates that somewhere in your system is a package that depends
on a pre-8.2 version of libpq. The error message should have told
you which package (or packages) that is. You can either remove it/them,
if they are packages you don't need; or look for updated versions.
One of the good things about open source is you can fix this kind of
problem yourself. If some of those packages *are* things you need, and
you can't find updated versions, just get the source RPM (SRPM) and
rebuild them yourself after installing the newer postgresql-libs.
