Great! + /* + * Walreceiver sets this latch every time new WAL has been received and + * fsync'd to disk, allowing startup process to wait for new WAL to + * arrive. + */ + Latch receivedLatch; I think that this latch should be available for other than walreceiver - startup process communication. For example, backend - startup process communication, which can be used for requesting a failover via SQL function by users in the future. What about putting the latch in XLogCtl instead of WalRcv and calling OwnLatch at the beginning of the startup process instead of RequestXLogStreaming?
