I think the bigger issue is that these patches bypass the normal
workflow of implementing changes in Postgres --- specifically, asking
about Desirability first:

    https://wiki.postgresql.org/wiki/Todo
    Desirability -> Design -> Implement -> Test -> Review -> Commit

It would have been much cleaner to discuss the desirability of this
change on its own.
