+ Appends @ and the database name to the user name when
+ connecting to the database. This allows per-database users.
+ User names ending with @ are considered global and may
+ connect to any database. It is recommended you create at least one
+ global user, e.g. postgres@, before enabling this feature.
+ Also, when creating user names containing @, you will need
+ to quote the user name.
