Hello Postgres Community,
My PostgreSQL is a cluster that managed by Patroni and etcd. While it has 2 replica server both of the replica's are holding huge amount of WAL file (current 55GB since 29th April). I've checked the replay delay, wal_keep_size, replication slot, max_wal_size but all of them were fine there's no slot keeping that wal in replica for sure even in master there's no slot holding that WAL, wal_keep_size is 5GB and max_wal_size is 8GB and delay is almost 0.02 second almost no delay. But there's no that size of WAL in master node. What's the troubleshoot of this case, how to check it?
Sincerely,
Mendbayar A.
