I have tried both default Postgres from the chart and external and crunchdata-postgres - in all cases, there is a connection problem

[Asgoret]

Same story. U found workaround?

[Asgoret]

Just wait for migrations...what migrations? Where?

[batazor]

@Asgoret see https://github.com/grafana/oncall/blob/dev/helm/oncall/values.yaml#L382-L389

[Asgoret]

@batazor don't get it...disable migrations?

[batazor]

@Asgoret The other services expect it to complete, even with migration turned off, so I don't think this is a workable option (I tried it, didn't work)
