I have never come across any custom postfix operators in the wild, and
I've never even seen ! used in practice.
So I would suggest a very short deprecation period. Deprecate now in
13, let 14 go by, and rip it all out for 15. That should give us enough
time to extend the deprecation period if we need to, or go back on it
entirely (like I seem to remember we did with VACUUM FREEZE).
