Tom Lane 4dab3d5ae1 Change the autovacuum launcher to use WaitLatch instead of a poll loop. ... In pursuit of this (and with the expectation that WaitLatch will be needed in more places), convert the latch field that was already added to PGPROC for sync rep into a generic latch that is activated for all PGPROC-owning processes, and change many of the standard backend signal handlers to set that latch when a signal happens. This will allow WaitLatch callers to be wakened properly by these signals. In passing, fix a whole bunch of signal handlers that had been hacked to do things that might change errno, without adding the necessary save/restore logic for errno. Also make some minor fixes in unix_latch.c, and clean up bizarre and unsafe scheme for disowning the process's latch. Much of this has to be back-patched into 9.1.
