I was considering this stuff again, and I got cold feet regarding the
fact that we may be able to hit the case of a collation not set if the
type is collatable depending on how the restrictions now in place for
partition bound expressions get lifted in the future, so I have
committed what you sent as v1, after changing the first error message
to use "partition bound expression" and after adding a comment on top
of the new checks.
