I think we've seen something like this before in connection with
readline/libedit follies.  Does the crash go away if you invoke
psql with "-n" option?  If so, exactly which version of readline or
libedit are you using?

FWIW, I do not see this on a fully up-to-date 10.4.8 G4 laptop.
I see

$ ls -l /usr/lib/libedit*
-rwxr-xr-x   1 root  wheel  112404 Sep 29 20:59 /usr/lib/libedit.2.dylib
lrwxr-xr-x   1 root  wheel      15 Apr 26  2006 /usr/lib/libedit.dylib -> libedit.2.dylib
$

so it seems that Apple did update libedit not too long ago ...
