Bumping catversion due to changes to pg_trigger and pg_rewrite.

BTW, the comment in this file says that we hope we never have more than
10 catversion changes per day, but to even make this possible we should
start counting at zero, shouldn't we?

The comment says "hopefully we'll never commit ten independent sets of
catalog changes on the same day" (not > 10), so the comment isn't wrong.
But I guess there wouldn't be any harm at starting at zero...

Since the entire catversion number is used as an integer, counting 0...9
vs. 1...0 makes quite a difference. And that difference manifests itself
 >9, not >10.

Sheesh ... yes, rereading your remark I get it. The comment is correct,
because the problem case is "10", no more and no less.
