What we ought to do here is forbid DROP NOT NULL on the table test.
See here for example:
https://www.postgresql.org/message-id/21633.1448383428@sss.pgh.pa.us
So this is a known limiration, and there have been some discussions
about removing this limitation in the backend, like here:
https://www.postgresql.org/message-id/CAKOSWNkN6HSyatuys8xZxzRCR-KL1OkHS5-b9qd9bf1Rad3PLA@mail.gmail.com
But there is no concrete patch lately. I don't think it would be
*that* complicated to get a rebased and polished version of what has
been proposed. It just needs care and time.
