Hello, I know there is a tool `pg_archivecleanup`, but it only accepts wal filename. What if I want to clean up all archived wal before a specified datetime?
That is dangerous, given that a WAL is important not based on its age but on whether it's content is still needed.
It would help to know what it is you are trying to achieve?
Though I could check the ctime fo each wal and figure out which to remove, but it looks like not a elegent way to do this. Also I tried to parse each wal and compare with the specified datetime in a binary-search way, but it is based on the fact that every COMMIT time in wal is sequential, but it looks like not the case.. Hence I wonder what is the best practice for this task? Thank you in advance! --- Magodo
