Is there any reason the pgbouncer replica is not modifi-able?

[y-tee]

Hi, we are looking to modify the helm chart make pgbouncer replica>1 to prevent the single point of failure when draining k8 nodes.

Just want to check if there is any specific reasoning behind

charts/charts/airflow/templates/pgbouncer/pgbouncer-deployment.yaml

Line 77 in 732a0f0

replicas: 1
