Really?  It works fine for me:

regression=# create schema postgres;
CREATE SCHEMA
regression=# show search_path;
 search_path
--------------
 $user,public
(1 row)

regression=# select current_schemas(true);
       current_schemas
------------------------------
 {pg_catalog,postgres,public}
(1 row)

regression=# alter database regression set search_path = public, '$user';
ALTER DATABASE
regression=# \c -
You are now connected to database "regression".
regression=# show search_path;
   search_path
-----------------
 public, "$user"
(1 row)

regression=# select current_schemas(true);
       current_schemas
------------------------------
 {pg_catalog,public,postgres}
(1 row)

regression=#
