-- qbit-webhooks 1.0: the five webhooks_ tables (PostgreSQL).
--
-- Column names are the snake_case of the field names (WebhooksQBitConfig
-- snakeCaseColumnNames, the default). Hosts that configure securityFields add
-- those columns to webhooks_endpoint, webhooks_subscription and
-- webhooks_delivery. The unique keys matter: webhooks_delivery.dedup_key stops
-- an event being queued twice, and (delivery_id, attempt_number) on
-- webhooks_delivery_attempt is the claim that stops two replicas sending the
-- same attempt.
--
-- Foreign keys (named fk_<table>_<column>):
--   endpoint_secret.endpoint_id, subscription.endpoint_id -> endpoint  CASCADE:
--     an endpoint's secrets and subscriptions are its own configuration, so
--     deleting the endpoint (webhooks.admin) removes them.
--   delivery.endpoint_id, delivery_attempt.endpoint_id -> endpoint      RESTRICT:
--     delivery history keeps its endpoint; cancel and Delete Deliveries first.
--   delivery.subscription_id -> subscription                           SET NULL:
--     a delivery outlives the subscription that queued it.
--   delivery_attempt.delivery_id -> delivery                           CASCADE:
--     attempts belong to their delivery (Retention deletes both).
-- Existing databases: run webhooks-foreign-keys-upgrade.sql.
