I do not agree with these bits. What's the point of these per-relation stats
at this poitns. You're just duplicating the normal relation pg_stats here.
I really think we just should drop pg_stat_subscription_workers. Even if we
don't, we definitely should rename it, because it still isn't meaningfully
about workers.
This stuff is getting painful for me. I'm trying to clean up some stuff for
shared memory stats, and this stuff doesn't fit in with the rest. I'll have to
rework some core stuff in the shared memory stats patch to make it work with
this. Just to then quite possibly deal with reverting that part.
Given the degree we're still designing stuff at this point, I think the
appropriate thing is to revert the patch, and then try from there.
