Of course, "clean" is a relative term. While making a small bit of progress
working in tidbitmap.c earlier this week, I thought it useful to prototype
some things in the tidstore, at which point I was reminded it no longer
compiles because of my recent work. I put in the necessary incantations so
that the v32 tidstore compiles and passes tests, so here's a patchset for
that (but no vacuum changes). I thought it was a good time to also condense
it down to look more similar to previous patches, as a basis for future
work.
