One query in case of asynchronous replication with replication slots and no wal archiving if a slave node remains disconnected from master for more than wal_keep_segments, it will not be able to do the replication when it comes online.
Now my question is when the slave connects to the master again will the XLOG in master also keep on building as the slaves replication is stuck or postgres will remove the replication slot if it is not busy.
Postgres Version 10.4
