In sigusr1_handler, don't ignore PMSIGNAL_ADVANCE_STATE_MACHINE based on pmState. The restriction is unnecessary (PostmasterStateMachine should work in any state), not future-proof (since it makes too many assumptions about why the signal might be sent), and broken even today because a race condition can make it necessary to respond to the signal in PM_WAIT_READONLY state. The race condition seems unlikely, but if it did happen, a hot-standby postmaster could fail to shut down after receiving a smart-shutdown request. In MaybeStartWalReceiver, don't clear the WalReceiverRequested flag if the fork attempt fails. Leaving it set allows us to try again in future iterations of the postmaster idle loop. (The startup process would eventually send a fresh request signal, but this change may allow us to retry the fork sooner.) Remove an obsolete comment and unnecessary test in PostmasterStateMachine's handling of PM_SHUTDOWN_2 state. It's not possible to have a live walreceiver in that state, and AFAICT has not been possible since commit |
