You do have functions returning set of rows.

I have no idea about pipelined functions.

the Pipelined is the statement so the functions knows he is returning rows.

Yes, you can write functions returning rows in pl/pgsql - see the docs,
specifically the RETURN NEXT statement. Then the syntax is:

select * from my_function();

- the function takes the place of a table in the SELECT statement.
