I think basic refactoring logic would support taking common things out
of the individual catalogs and keeping them in a common structure,
especially when they are for amusement only and not needed in any
critical paths.  All the ALTER command refactoring and so on that's been
going on is also moving into the direction that for data definition
management, there should be mainly one kind of object with a few
variants here and there.
