Some of my investigation: https://sentry.io/organizations/omisego/issues/1787235126/activity/?project=1477673&query=is%3Aunresolved

I am guessing when we restart watcher-info it will try to ask for Postgres while it is not ready yet (I assume Postgres got restart as well). Not sure what is the solution to this. We can ignore the sentry error or try to make our Genserver smarter (?) to detect Postgres is not ready in init?

Confirmed related to deployment (did one new deployment on stress for 1.0.4-pre.2 and the report immediately shows)

From @arthurk , it can be caused by cloudsql-proxy gets restarted. (Some background, the stress deployment actually did not restart the pod for watcher-info nor the Postgres for the watcher-info as the image of stress was hardcoded.)
