Hi, Should the standby also have to follow the WAL rule during recovery? The current patch doesn't care about the write order of the data page and WAL in the standby. So, after both servers fail, restarting the ex-standby by itself might corrupt the data.
If the standby follows the WAL rule, walreceiver might delay in writing WAL records until the startup process' or bgwriter's fsync have been finished. I'm a bit concerned that such delay might increase the performance overhead on the primary. Thought?
