SQL requires that no table in a view declaration be a temporary table.

I don't think this is a good idea. Especially since our temp tables are
allowed to shadow persistent tables, it would not be obvious whether the
view you're creating with any given statement will become persistent or
temporary.
I think an explicit CREATE TEMPORARY VIEW command would be fair and safe,
but until that is done we should probably concentrate on the SQL standard
behaviour.
