All the code that runs in the startup process to write WAL records before that's allowed generally is now consecutive, so there's no reason to shut the facility to write WAL locally off and then turn it on again three times in a row. Unfortunately, this requires a slight kludge in the checkpointer, which needs to separately enable writing WAL in order to write the checkpoint record. Because that code might run in the same process as StartupXLOG() if we are in single-user mode, we must save/restore the state of the LocalXLogInsertAllowed flag. Hopefully, we'll be able to eliminate this wart in further refactoring, but it's not too bad anyway. Amul Sul, with modifications by me.
