-- The following three UNIQUE indexes work together to enforce the user identity model:
|
|
--
|
|
-- 1. Users can be either local (provider_identifier is NULL) or from external providers (provider_identifier set)
|
|
-- 2. Each external provider identifier must be unique across the system
|
|
-- 3. Local usernames must be unique among local users
|
|
-- 4. The same username can exist across different providers with different identifiers
|
|
--
|
|
-- Examples:
|
|
-- - Can create local user "alice" (provider_identifier=NULL)
|
|
-- - Can create external user "alice" with GitHub (name="alice", provider_identifier="alice_github")
|
|
-- - Can create external user "alice" with Google (name="alice", provider_identifier="alice_google")
|
|
-- - Cannot create another local user "alice" (blocked by idx_name_no_provider_identifier)
|
|
-- - Cannot create another user with provider_identifier="alice_github" (blocked by idx_provider_identifier)
|
|
-- - Cannot create user "bob" with provider_identifier="alice_github" (blocked by idx_name_provider_identifier)
