PostgreSQL will request .history files when doing recovery and will keep requesting them, by default, until it finds that one isn't there- it will then target the last timeline that it found to perform replay to (target timeline = latest). We do also look for .history files when going through the promotion process and similarily will keep checking for timeline files until we don't find one and then that's the timeline we will move to for the promotion and we'll then immediately push a new .history file into the archive to 'claim' that timeline. Basically, it's not an error and it's entirely intentional that it works that way and your restore command probably shouldn't be complaining about it really (and that's where the actual 'No such file or directory' bit is coming from- not from PG itself). > I get that there was an issue, but with more details explained.

Not following this bit at all. There being a message about PG not finding a .history file during restore or promotion isn't actually an indication of anything having gone wrong or that the replica is out of sync. In other words, I don't know that you needed to actually do anything. Is there some reason you think you did need to do something beside that message being in the log..? Thanks, Stephen
