I don't see one single one of those subdirectory names that I'd call
self-documenting. Are you proposing we rename them all with carpal-
tunnel-syndrome-promoting names?
There's certainly some case to be made for renaming at least one of
"pg_subtrans" and "pg_multixact" so that these three similarly-purposed
subdirectories can all have similar names. But I think on the whole
that's (a) fixing what ain't broken, and (b) making it even more unlikely
that we'll ever get to consensus on changing anything. We've managed to
agree that we need to change the names ending in "log"; let's do that
and be happy that we've removed one foot-gun from the system.
