Re: [ADMIN] wal_level not changing - Mailing list pgsql-admin

Tried but does not work.

I see below output when I check the status of the service.

systemctl status postgresql-9.6

Hi,

update pg_settings set reset_val='minimal' where name='wal_level';

ERROR:  parameter "wal_level" cannot be changed without restarting the server

 

set wal_level='minimal';

ERROR:  parameter "wal_level" cannot be changed without restarting the server

update pg_settings set setting='minimal' where name='wal_level';

ERROR:  parameter "wal_level" cannot be changed without restarting the server

Even after restarting and reloading the server multiple times the setting does not update and remains as below:

show wal_level;

+-----------+

| wal_level |

+-----------+

| replica   |
