Hi ,

Ensure the following:

• Replication is functioning correctly between the primary and secondary servers, with no lag.

• The archive_command parameter is properly configured in the database settings.

Hello Community,

Although the WAL retaining settings are default (max size 1GB),
`wal_keep_segments` is 25, checkpoint target is 2.5 minutes(default).
I noticed a few WAL files in secondary nodes (streaming replication) `pg_xlog`
folder.

What could be the reason why postgresql did not delete these ?

Thank you
Regards
Mohan
