Yeah, I mentioned in [1] about that and took measures there to keep
the old name in place.  In the latest patch, there's an entry in
map_old_guc_names[] to allow the old name to work. I think the
buildfarm will still work ok because of that.

What I'm not so sure about is how to go about getting all owners to
change the config for versions >= PG16. Is that a question of emailing
each owner individually to ask them if they can make the change? Or
should we just forever keep the map_old_guc_names[] entry for this?
