You should look into why the filesystem seems to have lost part of your WAL file --- that strongly suggests that the disk or kernel is lying about write ordering, which will cause you problems eventually. But this message per se will go away as soon as the WAL endpoint moves another 1.5Mb. Unless there's other corruption elsewhere you'll be fine. regards, tom lane
