Proposed relaxation of CREATE RULE syntax

I suggest that the CREATE RULE syntax be relaxed so that
it is legal to have a list of SELECT commands in a rule.

I'll argue that:
1) The change is simple (2 lines in gram.y). Diff is
attached.
2) It breaks nothing (more things become legal)
3) It makes the parser agree with the published syntax,
which currently makes no distinction about SELECT
commands.
4) It makes the language more "regular" in that SELECT
commands are no longer special.:

Diff is an attachment because of line-wrapping. I'm new
here
so I don't know if this works. But as I said it's only 2
lines.
