This could be a bug in psql, a buggy/damaged readline library, etc.

For GUI apps Mac OS X makes a crash record in the system logs. I'm not 
sure if it does that for command line apps too - I think it does. Can 
you check "Console" and see if there are any crash dumps for psql?

If not, to find out what's going on it may be necessary to attach a 
debugger. This probably isn't installed on your computer. You would need 
the Developer Tools (XCode etc), which can be obtained from the Apple 
web site as a free download.

I don't have access to Mac OS X 10.6, but maybe someone else here does 
and can reproduce the issue. Even if they can, it might still be helpful 
to get some additional info on the crash you're having, so it'd be great 
if you could grab the developer tools and reply once they're installed. See:

   http://developer.apple.com/technologies/xcode.html

You need a "dev center" username/password, but it's free to register and 
they don't spam you. See:
