Not quite an objection, but...

If you change this warning title then it becomes the odd one out -
every other warning in all the pg docs just says "Warning". IMO
maintaining consistency throughout is best. e.g. I can imagine maybe
someone searching for "Warning" in the docs, and now they are not
going to find this one.

Maybe a safer way to fix this "silly otherwise-empty section title"
would be to just add some explanatory text so it is no longer empty.
