Hi!
Is there any plan to add implicit declaration of returning parameters
for functions?
Something like:
create function list(in a int) returns setof implicit record as
$$
if a=1 then select * from table1;
else select * from table2;
end if;
$$
languge sql;
which would than dynamically create

You can use a SETOF function as:
CREATE OR REPLACE FUNCTION

Think about what happens if you use
You can use it as:
SELECT * FROM get_test_data(1000) AS t1 (emp_name VARCHAR);
