Hmm. We have heard that reported on OS X because of a bug in Apple's
version of libedit, but not on any flavor of Linux. Your tests seem
to eliminate libreadline as the cause anyway. Might be a corrupt
copy of libpq --- have you tried reinstalling that?

That's normal on Linuxen, because "ulimit -c 0" is usually the default
setting. Please try "ulimit -c unlimited", and then if you get a core,
send a backtrace. The last few lines of an "strace" watching the psql
run might be useful as well.
