Dear Adrian,
If we set parameter *"PG-WAL = replica"* in PG13 conf file , there is
any issue in replication through PG_WAL and pg_log_archive log.
In versions of Postgres from 9.6+ your setting of hot_standby is mapped
to the replica setting so it is really not a change. In other words the
hot_standby setting = replica setting as of 9.6. I made the suggestion
to change just so the conf setting matches the choices in current
documentation. Less confusion for someone looking through the
postgresql.conf file and then looking up the values in the documentation.
As to your replication is that binary replication or logical replication?
Also you have not said where you are measuring the size growth in WAL files?

Salve server replicate from PG_WAL and DR system replicate from

Where are you measuring this in the WAL directory or the archive directory?
Do you have replication set up from this server and if so what type?
FYI, the wal_level setting of hot_standby is deprecated and maps to
replica since version 9.6. At some point you might want to change to
match current documentation.
