Well, we've got this:

regression=> select session_user;
 session_user
--------------
 dot.net
(1 row)

which is reasonable: that output shouldn't be quoted.
But then:

regression=> select 'dot.net'::regrole;
ERROR:  invalid name syntax
LINE 1: select 'dot.net'::regrole;
               ^

which is also reasonable.  So you need to provide the quoting if
you want to interface these.

regression=> select to_regrole(quote_ident(session_user));
 to_regrole
------------
 "dot.net"
(1 row)

select oid from pg_roles where rolname = session_user
