change alter user to be a true alias for alter role

the doc say:

> ALTER USER is now an alias for ALTER ROLE<http://www.postgresql.org/docs/devel/static/sql-alterrole.html>
> .

but alter user lack the following format:

> ALTER ROLE name [ IN DATABASE database_name ] SET configuration_parameter{ TO | = } {
> value | DEFAULT }
> ALTER ROLE { name | ALL } [ IN DATABASE database_name ] SET
> configuration_parameter FROM CURRENT
> ALTER ROLE { name | ALL } [ IN DATABASE database_name ] RESET
> configuration_parameter
> ALTER ROLE { name | ALL } [ IN DATABASE database_name ] RESET ALL

attach patch add the per database set for alter user:
ALTER
USER
name [ IN DATABASE database_name ] SET configuration_parameter { TO | = }
{ value | DEFAULT }
ALTER
USER
{ name | ALL } [ IN DATABASE database_name ] SET configuration_parameter FROM
CURRENT
ALTER
USER
{ name | ALL } [ IN DATABASE database_name ] RESET configuration_parameter
ALTER
USER
{ name | ALL } [ IN DATABASE database_name ] RESET ALL

this make alter user a true alias for alter role.
