Doesn't anyone have any idea what might be happening? I have a real
problem with PostgreSQL on 2.0 and I can't even get a core file. I
tried creating a new kernel with INSECURE set hoping that that was the
problem but it made no difference.
If no one can help with this, does anyone have any idea why PostgreSQL
would suddenly start getting into a busy loop in 2.0 but not RC4 or
