I updated the error messages to match the new "unified" style, adjust
a couple of comments, and pushed.  Thanks to all the people who
tested.  I'll keep an eye on the build farm.

Commits

  1. Add kqueue(2) support to the WaitEventSet API.

  2. Add WL_EXIT_ON_PM_DEATH pseudo-event.

  3. Be conservative about alignment requirements of struct epoll_event.

  4. Make idle backends exit if the postmaster dies.
