That's another possibility. It's not real clear that there's any
advantage to storing rules in preparsed form to begin with --- if
we just stored the original text and reparsed it each time it was
read, the system would be vastly more flexible, and probably not
noticeably slower.
Right now the parser doesn't really support this: there's no way to
extract the portion of the original query string that corresponds
to the body of the CREATE RULE/VIEW command. But that could be fixed
with some straightforward hacking...
