Users & Roles

A Postgres cluster is configured with three users when created:

  • postgres - a role with superuser and login privileges that was created for you along with the cluster. Since the postgres role has superuser rights, it's recommended that you only use it for admin tasks and create new users with access restricted to the minimum necessary for applications
  • flypgadmin - this role is used internally by to configure and query the Postgres cluster
  • repluser - this is the user replica servers use for replication from the leader

You can view a list of users using flyctl:

fly postgres users list -a pg-test
Running flyadmin user-list
flypgadmin true      postgres
postgres   true      postgres
repluser   false     postgres
