On the publisher, it was assumed that an INSERT change cannot happen for a relation with no replica identity. However this is true only for a change that needs references to old rows, aka UPDATE or DELETE, so trying to use logical replication with a relation that has no replica identity led to an assertion failure in the publisher when issuing an INSERT. This commit removes the incorrect assertion, and adds more regression tests to provide coverage for relations without replica identity.
