Yeah, I'm not sure what's causing that. Since that comes from a debugging function, we could work around it, but it would be nice to understand why, so I'll probably have to experiment on my CI repo.

It was a quick way to define some things only once, so they probably all showed up in the list of things you found not undefined. It's different from the style of simplehash.h, which is to have a local name and #undef for every single thing. simplehash.h is a precedent, so I'll change it to match. I'll take a look at your list, too.

I think we can work mostly simultaneously, if you work on tid store and vacuum, and I work on the template. We can always submit a full patchset including each other's latest work. That will catch rebase issues sooner.
