I agree. I think it's too late to be working out fine details around
TOAST like this. This is a patch that touches the storage format in a
fairly fundamental way.

The idea of turning WARM on or off reminds me a little bit of the way
it was at one time suggested that HOT not be used against catalog
tables, a position that Tom pushed against. I'm not saying that it's
necessarily a bad idea, but we should exhaust alternatives, and have a
clear rationale for it.
