Hi David,
Thanks for clarification
> I prefer TABLE.  Using setof is more useful when the returned type is
predefined
But in the table also isn't the returned type predefined? Example:
CREATE FUNCTION fun1(integer)
RETURNS TABLE(
        col1 integer,
        col2 text
)
AS 'MODULE_PATHNAME', 'fun1'
LANGUAGE C;
We know the returned type will have two columns with type -  integer and
text. Am I correct?

> Or a true record where the caller has to specify the shape.
Sorry but didn't get this shape part?

Thanks
