FWIW, I think it might be worthwhile to convert postmaster into a loop over a process local latch, with that latch being set in signal handlers. My feeling is that that'd simplify the code rather significantly. I'm not 100% it's worth the code churn, but it'd definitely be easier to understand. Thread sanitizer isn't the first analysis tool that has problems coping with forks in signal handlers btw, valgrind on amd64 for a long while had misaligned stacks in the children afterwards leading to very odd crashes.
