Need help on understanding of wal_keep-segments and max_wal_size dependency.

[Swati yadav <Swati.Yadav@xxxxxxxxxxx>]

Hello Team

We are using streaming replication without  feature archiving and replication slots.

Could you please help us in understanding how replication will works when I set max_wal_size to 1GB, wal_keep_segments  set to 300​.

​In this scenario, replication is getting failed.  Could you please brief us the causes of failure and how can we fix this issue, apart from using the feature archiving​ and replication slots.

Thanks & Regards
