Let me explain what I did to adjust the release notes.  I took your
commit hashes, which were longer than mine, and got the commit subject
text from them.  I then searched the release notes to see which commit
subjects existed in the document.  Only the first three did, and the
release note item has five commits.

The then tested if the last two patches could be reverted, and 'patch'
thought they could be, so that confirmed they were not reverted.

However, there was no text in the release note item that corresponded to
the commits, so I just removed the entire item.

What I now think happened is that the last two commits were considered
part of the larger NOT NULL change, and not worth mentioning separately,
but now that the NOT NULL part is reverted, we might need to mention
them.

I rarely handle such complex cases so I don't think I was totally
correct in my handling.  Let's get a reply to Peter Eisentraut's
question and we can figure out what to do.
