oldest WAL files not removed
Hi, Looking at WAL folder after a crash, I noticed that new files after restarting overwrite the more recent files before the crash and not the oldest, which was what I expected. Is that normal ? I got only one file marked .deleted. Does that happens when a WAL file hase been completed updated in the database and if then while all oldest files aren't marked .deleted after restarting ? Example : Crash occurs Aug 31 22:03 which is the more recent Wal file, the oldest file is Aug 30 17:20 (and 105 files between those two) After restarting Aug 30 17:20 is still there, Aug 31 22:03 disappeared, one new file is Sep 1 12:15 marked .deleted (restarting date) and one new Sep 1 12:36 which I guess is normal. Right now, I see an new wal file and the previous one marked .deleted which is ok. Why are the oldest wal files still there ?? Can I remove them ? Hope I'm clear enough and thanks for explanations, Olivier
