If I understand what you are asking for, you don't.

plpgsql is not imposing this, the system as a whole does. Else, the
parser would have no idea what to expand "*" to in
select * from myfunc(42);
There are facilities that let you use the same textual function "myfunc"
for different result column sets, but this doesn't get you off the hook
of having to tell the calling query what the column set is going to be.
