scopes/types/scope.go
Port over Postgres storage and tests. Do the minimum possible port of the code from auth to get Postgres working and make the tests run and pass again. This leaves a bug where the ErrScopeAlreadyExists type, when populatd from Postgres, contains the entire error string returned from the database, instead of parsing the ID itself out. Which is a thing we should do and add a test for.
