Yeah, I think we discussed that once before. I have no particular
objection to doing that in HEAD, just think it's a bit late for 9.2.
In any case, it will only help for medium-size numbers of entries;
once you get to enough tables/functions/whatever that a seqscan of the
catalog is bad news, only fixing the name matching is going to help.
