Re: WAL segment management on a standby

Thanks Matheus,

What I guess I'm more than curious about is as this is one of two standbys and I could always rebuild it again from either of the other two machines, is what am I risking if delete everything except maybe the last handful of WAL segments? When I start the database, I usually only see one or maybe two references to WAL segments being used to sync up. And being that the standby streams anyway, I'm not all that concerned if another pg_basebackup has to run to rebuild the standby. I only want it to start cleanly in the event of a stoppage. Which almost never happens anyway.

Could I safely delete the *A1, *A2, and maybe even the *A3 files?

If you only care to storing files needed for backup made at 00000000300000000C000000A3, you can remove 00000000300000000C000000A1 and 00000000300000000C000000A2, but not the others.
