All of those (except FOREIGN) can be used as a column constraint as
well, and that might be necessary for a reason similar to the reason I
need to use a reserved word (i.e. they can come after a DEFAULT
expression). Is it possible that FOREIGN doesn't really have to be a
reserved word, but was just included because the others were?
I'm not an expert on the matter, but it does appear to compile and
recognize the grammar with EXCLUSION as an unreserved keyword. I'm in
the middle of changing a lot of things around, so I can't say that it
works beyond that.
