Is the syntax of CREATE RULE defined by the SQL standard (or modeled
on something else that is in the standard), or are we just making it
up out of whole cloth?
If it's defined by the standard then I think we have no choice but to
change psql.
If it's our own invention, I think switching to () might be a better
idea. I'm not that worried about changing psql, but I do wonder how
many other applications might "know" a similar amount about SQL
syntax...
