RE: Huge archive log generate in Postgresql-13

Dear Holger,

we have one slave server and one DR server.
salve server working on streaming replication and DR server replicate with Archive log.
if we change "wal_level " parameter value to “replica” there any impact in existing server (Salve and DR) replication?
Please suggest .

Regards,
Ram Pratap.

Grenting,
Is your logging set to high verbosity??

Usually use high verbosity for debugging, then change to low verbosity.

wal_level = hot_standby # minimal, replica, or logical
# (change requires restart)

Set wal_level to one of the allowed values. It's possible that your value gets interpreted as logical, thus creating larger wal entries.

Hi Support,

We have upgraded postgresql DB from version 11 to 13 . after upgrade to 13 huge archive log generate in system .
Before upgrade per day 120GB to 150 GB log generated but after upgrade per day approx. 250 to 300 GB log generated.
Can you please suggest why huge archive log generated after upgrade there any configure setting or this is Postgresql-13 behaviour.

Postgresql-13 Postgresql conf file attached for your references.
