As far as I can see, with the patch as it currently stands, you would
end up with only table "first" in the schema, which seems very
surprising to me.
Yeah, I think the second should die. CINE should only work if there are no
other objects created as part of the statement, IMHO.
Well, if that's the rationale then you end up with no schema foo at all
(i.e. both die), which seems even more surprising (though I admit it has
the advantage of being a simple rule to document.)
I think we should just disallow putting any contained objects in the
statement when IF NOT EXISTS is used. It's simple to understand, simple
to document and implement, and I think it covers all the sane use-cases
I thought we'd already agreed on this.
