auth
auth/session_test.go
Implement postgres version of authCodeStore. Create an authCodeStore that keeps data in Postgres. Again, we run into the problem where Scopes can't be stored in Postgres arrays, as discussed in 762953f6a7f2. I wish we could do better, but for now, it will suffice. We also added the postgres authCodeStore to our slice of authCodeStores to test when the correct environment variables are present. Wrote initialization SQL for the tables required by the postgres authCodeStore. Added SQL to the SQL script that empties our database, to properly empty our new tables.
