RE: Huge archive log generate in Postgresql-13

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.

https://www.postgresql.org/docs/13/runtime-config-wal.html

Regards,

Ram Pratap.

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.
