If so, we might want to also update the deprecation warning for the prefix !! operator in pg_operator.dat:
{ oid => '389', descr => 'deprecated, use ! instead',
oprname => '!!', oprkind => 'l', oprleft => '0', oprright => 'int8',
oprresult => 'numeric', oprcode => 'numeric_fac' },
That will be the only remaining factorial operator if we remove postfix operators.
