Andres Freund cbc47ad7ef Fix possibility of self-deadlock in ResolveRecoveryConflictWithBufferPin(). ... The tests added in 9f8a050f68 failed nearly reliably on FreeBSD in CI, and occasionally on the buildfarm. That turns out to be caused not by a bug in the test, but by a longstanding bug in recovery conflict handling. The standby timeout handler, used by ResolveRecoveryConflictWithBufferPin(), executed SendRecoveryConflictWithBufferPin() inside a signal handler. A bad idea, because the deadlock timeout handler (or a spurious latch set) could have interrupted ProcWaitForSignal(). If unlucky that could cause a self-deadlock on ProcArrayLock, if the deadlock check is in SendRecoveryConflictWithBufferPin()->CancelDBBackends(). To fix, set a flag in StandbyTimeoutHandler(), and check the flag in ResolveRecoveryConflictWithBufferPin(). Subsequently the recovery conflict tests will be backpatched.
