How to set the wal_level in AWS RDS Postgresql?

Problem

How do I know which wal_level my AWS RDS Postgres 11.1 database has?

I checked 'parameter groups', but was unable to find the wal_level.

Once found, how do I change it?

Solution

To find out the wal_level you can use PSQL and execute: show wal_level;
You need to set rds.logical_replication parameter to 1. It will automatically change wal_level to logical.

I found some details here
