You could shorten this right up and avoid the overhead of plpgsql by making it a pure SQL function without named
parameters:(change VOLATILE to STABLE unless you are actually changing something by selecting on those tables) 

CREATE OR REPLACE FUNCTION getrowstest3(character varying, character varying)

   RETURNS SETOF getrows AS

$BODY$
select
u.role_id,u.user_id,p.name,p.creation_date,p.telephone_number,p.email,p.remarks,p.city,p.state,p.country,p.postal_address,p.company_name,p.department_name,p.contact_person,


p.role_group,p.role_description,p.first_name,p.last_name,p.pincode,p.status,p.department_id,p.designation_id,r.role_name,r.right_edit,r.right_filter,r.right_search,r.right_browse,


r.right_print,r.right_download,r.right_admin_user,r.right_image_creator,r.right_vector_download,r.right_wps,r.right_queries_filter,r.right_google_map,r.right_user_management,

r.right_route_analysis,r.right_legend,r.right_treeview,r.insert,r.update,r.delete,r.query,r.lock from ksdi.user_roles
u,ksdi.principalsp,ksdi.roles r where p.PRINCIPAL_ID = u.USER_ID and 

r.role_id = u.role_id and p.name =$1  and p.password = $2
$BODY$

   LANGUAGE sql VOLATILE

   COST 100

   ROWS 1000;
