It's just occurred to me that this could break the buildfarm fairly comprehensively. I just took a count and we have 74 members using force_parallel_mode. 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.

Oops, I missed or forgot 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?

We'll email them once this is in. Most people are fairly reponsive.

cheers
