The pg_regress script sets LD_LIBRARY_PATH to try to cause libpq and
the other shlibs to be picked up from the temp installation tree.
Perhaps this is wrong or insufficient on your platform. It certainly
sounds like the dynamic linker is choosing the installed libpq over
the one that we want it to use. Any thoughts on fixing that?
