not easily, the RPMs that yum fetches have the library paths hard coded.
building postgres from source is actually very easy. just follow the
README and/or INSTALL in the source tarball. build it for an alternate
root path, like /usr/local/pgsql84/... (you'd specify this as an option
on the ./configure step), then after its built and installed to that
alternate path, and you've run initdb, you would edit postgresql.conf in
this alternate ./data directory to change the port to a different port,
such as 5433 instead of the default 5432.
