Fixes #131573

Release note (bug fix): Ordering by VECTOR columns now results in an
"unimplemented" error. Previously it would result in internal errors in
some cases. See #92165.

Encountered an error creating backports. Some common things that can go wrong:

1. The backport branch might have already existed.
2. There was a merge conflict.
3. The backport branch contained merge commits.

You might need to create your backport manually using the backport tool.
