Fujii Masao 946647f845 Make pg_promote() detect postmaster death while waiting for promotion to end. 
Previously even if postmaster died and WaitLatch() woke up with that event
while pg_promote() was waiting for the standby promotion to finish,
pg_promote() did nothing special and kept waiting until timeout occurred.
This could cause a busy loop.

This patch make pg_promote() return false immediately when postmaster
dies, to avoid such a busy loop.

Back-patch to v12 where pg_promote() was added.
