Patroni 不会更改 postgresql.conf 中的 wal_level

Question

I modify wal_level in patroini yaml file from replica to logical and ran the following commands. However, the value was not changed in postgresql.conf. What am I missing?

Is there a way to change DCS parameters? I even tried to use alter database so I will have an "auto" file but that did not help either.

Your help is most appreciated

patronictl -c postgres.yml show-config 
patronictl -c postgres.yml edit-config 
// I also did reload here to be of safe side and then restarted cluster
patronictl -c postgres.yml restart postgres-cluster

Postgres is run by Patroni with the following parameters:

ps -ef | grep postgres

When I ran the patronictl -c postgres.yml edit-config the parameters section was not indented. Once I ran the command patronictl -c postgres.yml edit-config with -p option it put it in the correct indentation and now it works.
