Tom Lane b23cd185fd Remove logic for converting a table to a view. ... Up to now we have allowed manual creation of an ON SELECT rule on a table to convert it into a view. That was never anything but a horrid, error-prone hack though. pg_dump used to rely on that behavior to deal with cases involving circular dependencies, where a dependency loop could be broken by separating the creation of a view from installation of its ON SELECT rule. However, we changed pg_dump to use CREATE OR REPLACE VIEW for that in commit d8c05aff5 (which was later back-patched as far as 9.4), so there's not a good argument anymore for continuing to support the behavior. The proximate reason for axing it now is that we found that the new statistics code has failure modes associated with the relkind change caused by this behavior. We'll patch around that in v15, but going forward it seems like a better idea to get rid of the need to support relkind changes.
