Hello, I think the business with an evergrowing on_exit list needs a different solution than a gigantic array of entries. Maybe it would make sense to restructure that code so that there's a single on_exit item, but there exists a list of per-database entries to clean up which are all done in one call of the function. Then you don't need to change the hardcoded MAX_ON_EXIT_NICELY array size there.
I think it would be better to have a preparatory 0001 patch that just moves the code to the new files, without touching anything else, and then the new feature is introduced as a separate 0002 commit. You still have a bunch of XXX items here and there which look to me like they need to be handled before this patch can be considered final, plus the TODOs in the commit message. Please pgindent.
