Update metadataConnection to be postgres container default.

The local postgres container password default does not seem to be correct.
Updated this so the airflow containers will be able to access the database.

@ianstanton related to switching the postgres subchart maybe?

[ianstanton]

Hmm that value should be set here:

airflow/chart/values.yaml

Line 698 in 2a2adb3

postgresqlPassword: postgres

I'll take a closer look

@madden1706 Could you provide steps to reproduce and environment details? I am able to run successfully with default values on a GKE cluster. Thanks!

Hi, I've deleted and recreated my minikube cluster. Seems to have solved - I'll close this.
