I took a look over each of these.  +1 for all.  Thank you.

Commits

  1. Remove obsolete check in SIGTERM handler for the startup process.

  2. Centralize logic for restoring errno in signal handlers.

  3. Check that MyProcPid == getpid() in backend signal handlers.

  4. Avoid calling proc_exit() in processes forked by system().
