This is a version-skew issue: you are trying to use a psql executable
with a libpq.so library that's older or newer (I forget which) than the
psql executable is.

On Fedora (and other Linuxen) you should basically never rely on
LD_LIBRARY_PATH, for exactly the reason you're seeing here: programs
work or fail depending on environment. The correct way is to set up
the ldconfig search path to include directories where shared libraries
exist.
Also, it'd probably be a good idea to make sure you have only one set
of Postgres executables+shared libraries on the machine. You've
evidently got at least two :-(
