title: Two owners of the same PostgreSQL database
body: <p>Is it possible with Postgresql to create a database which has 2 users which act like owners to the database?</p>
  
  <p>I can create a group role and add both users to that group, and then make the group the owner of the database, but this requires both users to be have to manually set their role on every connection to make any tables they have created accessible to the other user.  Is there any way to make the group be the default role for a user each time they log in or any other way to achieve the same thing?</p>
