ducky/subscriptions/postgres.go

Export all subscriptionStore methods. We're not going to wrap all our subscriptionStore interactions in a Context type, so we need to expose all the functions so other packages can call them. Also, it's now SubscriptionStore. Also creates a SubscriptionRequest type that is used to create a new Subscription instance, along with a Validate method on it, to detect errors when creating a SubscriptionRequest. Update our CreateSubscription function to be New, and have it take a SubscriptionRequest, a Stripe instance, and a SubscriptionStore as arguments. It'll create the Subscription in the SubscriptionStore, create a customer in Stripe, and create the subscription in Stripe, then associate the Stripe subscription with the created Subscription. Also, fix our StripeSubscriptionChange function to correctly equate a missing/zero Unix timestamp from Stripe with a missing/zero time.Time.

20 // our subscriptionStore interface on Postgres). Note that the
21 // value of a Postgres variable contains a _pointer_ to an sql.DB
22 // pool of connections, so it's not necessary to use the address of
23 // the Postgres variable itself (though there shouldn't be any harm
24 // in doing so).
