title: why does permissions in one database affect another with same schema?
body: <p>I have database A and B and user app_user. They both have the schema public. I granted read access to database A for app_user. When my application runs, it complains that "relation does not exist". When I login as that user into db A, I can indeed select from tables. Next I deleted the database B entirely and now my application runs.... ???? This is a rails app running on a postgres DB by the way. The rails app is pointing to db A based on config.</p>
