This is a known and oft-reported bug in OS X's libedit --- it stomps on
memory that doesn't belong to it anytime the number of possible
completions is exactly 9 + 10*N, for any N>=0. Complain to Apple:
the fix was applied upstream quite some time ago, and they are being
derelict by not adopting it. In the meantime, you might consider
building psql with readline instead of libedit. (Note you need real GNU
readline, as /usr/lib/libreadline.dylib is just a link to libedit.)
