Tom Lane 9fdc49d08f Fix CREATE VIEW to allow zero-column views.
We should logically have allowed this case when we allowed zero-column
tables, but it was overlooked.

Although this might be thought a feature addition, it's really a bug
fix, because it was possible to create a zero-column view via
the convert-table-to-view code path, and then you'd have a situation
where dump/reload would fail.  Hence, back-patch to all supported
branches.

Arrange the added test cases to provide coverage of the related
pg_dump code paths (since these views will be dumped and reloaded
during the pg_upgrade regression test).  I also made them test
the case where pg_dump has to postpone the view rule into post-data,
which disturbingly had no regression coverage before.

Report and patch by Ashutosh Sharma (test case by me)
