Re: BUG #17567: Unable to Set Max_Connection in Postgresql which has replicas

Hey,
It is not a bug.
If you are using patroni, you should change your parameters in patroni
configuration yaml file, so the changes are reflected in your Distributed
Configuration Store. If you would look at the Patroni documentation (
https://patroni.readthedocs.io/en/latest/SETTINGS.html) you can find a
note, that parameters like max_connections are stored in DCS and applied on
all Patroni nodes overwriting settings from postgresql.conf. Also if
Postgres was bootstrapped by Patroni, postgresql.conf itself should have a
note:

# Do not edit this file manually!
# It will be overwritten by Patroni!

Hope it helps.

Cheers,
Mateusz
