Tom Lane a32ca78836 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) Discussion: https://postgr.es/m/CAE9k0PkmHdeSaeZt2ujnb_cKucmK3sDDceDzw7+d5UZoNJPYOg@mail.gmail.com		2019-02-17 12:37:31 -05:00
