Wait. A. Minute. This patch seems totally unacceptable for backpatching.

Was there any real discussion of whether we could get away with that
in the back branches? My opinion is no. It's not even clear to me
that this is acceptable in HEAD --- isn't it going to create huge
problems for pg_upgrade?
Perhaps some solution to the compatibility problems could be found
based on giving the cube extension a new version number, and applying
the behavioral change only upon doing ALTER EXTENSION UPDATE. But
it doesn't look like the patch even bumped the extension's version
number.
I do not think this patch was ready to commit.
