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.
