You need to worry, very much, that your setup did not preserve data write ordering when the power went out. - you might have fsync turned off in PG - you might be using a non-journaled filesystem - your disks might be cheating on sync commands (consumer grade disks are notorious for this) - you might be using consumer-grade flash that can't flush its cache on power loss This highly unlikely to be a PG bug, and you do need to worry that it could have been the master if you had been less lucky. -- Scott Ribe scott_ribe@xxxxxxxxxxxxxxxx https://www.linkedin.com/in/scottribe/ > On Jun 28, 2018, at 7:17 AM, Vijaykumar Jain <vjain@xxxxxxxxxxxxx> wrote: > > My only concern was do I need to worry about this error showing up again?
