+1 I'm hoping we can fix PM death handling soon, and then I assume this can go straight back in without modification. CVs are an essential low level synchronisation component that really should work in lots of environments, but we need to straighten out some historical mistakes and rough edges. Commit cfdf4dc4 removed open-coded exits to fix a lot of bugs of omission, but it failed to fully consider all the consequences of "composition", ie hiding that behaviour out of sight. We really need a sort of postmasterless PANIC here, and I am happy to work on that (see new thread), not least because it aligns better with the behaviour of a multithreaded server. There, the answer is "what other backends?" so I'd already been looking sideways at system states including the lingering logger, lingering query execution and the special but inherently flaky error reporting in a few spots.
