Maybe we need to keep force_parallel_mode as an alternative spelling for debug_parallel_query until we can get them all switched over. I know it's more trouble ...
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?
