How to return a record set from function.

Dear Friends,

I am newbie to Postgres. I am running 7.3.4 on Linux 7.3. I am using Pgadmin tool. I need to return the table rows via record set.

Create table t1 (c1 int, c2 varchar, c3 varchar);

Create or Replace function sel_t1 () returns setof records as '
select c1, c2, c3 from t1;
' Language SQL;

It was fine and created a function. while i execute it as

select sel_t1;

I got the following error.

ERROR: Cannot display a value of type RECORD

How to solve this. Please help.
