+1. I don't have a huge problem with excluding a few key catalogs for
which we think it might be unsafe, but in general it seems like a good
idea to settle on a policy of including them everywhere else.
Omitting one or even half a dozen TOAST tables on system catalogs
doesn't save anything material for users, but does succeed in annoying
some user who is trying to do something a little off the beaten path.
It also doesn't save anything for developers; indeed, the cognitive
load comes mostly from having to argue about which things should get
TOAST tables. If we just add them everywhere, we can stop arguing
about this; no other policy will have that effect.
