Hi friends,

Anybody let me know how to automate the archive clean up in postgres.

If the only reason you have an archive is so a standby can get the WAL, then you can just use a slot instead.  If you don't have an archive, you don't need to clean it up.

If you are using the archive for something else, you would need to tell us what that is.  Otherwise, you are just asking "how long is a piece of string"?

Cheers,

Jeff

No, archives are critical for online backups and PITR, not just so that
you can make sure the standby is able to catch up (but that's a very
nice additional bit that archives provide).

Yes.
