How do you install a jdbc plugin? Is the postgres plugin not available by default? If I use the database sink's example config (plugin name: postgres, plugin type: jdbc), my pipeline can't be deployed. I get an error saying I need to install the jdbc plugin for postgres.
Update: I eventually found the hub button had a menu for installing plugins. I installed the PostgresSQL and the JDBC (first 8, then 7) drivers. I'm still getting the same error.
