python - How to return resultset with Plpython3 in Postgres -

-

how can plpython function return result set normal sql query resultset (not text).

here function definition - 

drop function if exists demo_report(); create or replace function demo_report()     returns setof <what-type> $$     rv = plpy.execute("select * test")     return rv $$ language plpython3u;

when execute select demo_report(); should return resultset client rather text.right getting text - enter image description here

i using postgres 9.2 plpython3u on windows.

i found way desired result - table : 

create table public.test (    id serial not null,    name   varchar(200) not null check (name <> ''),    salary int,    created  date,    constraint id primary key (id), )  (   oids = false,   autovacuum_enabled = true );

my plpython3u function - 

create or replace function demo_report()   returns setof test $$   resp = []   rv = plpy.execute("select * test")   in rv:     resp.append(i)   return resp  $$ language 'plpython3u' volatile;

and query - 

select * demo_report();

now getting desired response - enter image description here

its been quite nice journey plpython till now. enjoying it.
