<para>
This allows per-database user names. You can create users as <literal>
username@dbname</>. When <literal>username</> is passed by the client,
<literal>@</> and the database name is appended to the user name and
that database-specific user name is looked up by the server.
When creating user names containing <literal>@</>, you will need
to quote the user name.
</para>
<para>
With this option enabled, you can still create ordinary global
users. Simply append <literal>@</> when specifying the user name
in the client. The <literal>@</> will be stripped off and looked up
by the server.
