Hi Alexander,

Heikki spotted a misplaced wake-up call for replay waiters in
PerformWalRecovery. He suggested that the WaitLSNWakeup needs to be
invoked immediately after wal record is applied to avoid the potential
missed wake-ups when recovery stops/pauses/promotes. It makes sense to
me. Please check the attached patch to fix that.
