We've had several complaints about that tab-completion bug in the Apple-supplied version of libedit, most recently here: http://archives.postgresql.org/pgsql-bugs/2011-06/msg00119.php
I had a bug filed with Apple about that, and today I got some auto-mail indicating they'd fixed that bug as of OS X 10.7 (Lion).

So, if any early adopters want to try it out ... regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
