If you could find a way to pass a value of type some_table into the

Oh, I didn't think about that. Maybe I'll try it.
What I ended up with is this:
CREATE FUNCTION ... (
) RETURNS SETOF text ...
...
RETURN QUERY EXECUTE format(
'SELECT row(t.*)::text FROM %I.%I AS t'
, ...
);
So the function is getting a record and casting it to text. To call the
function you have to...
SELECT (function(...))::name_of_table).*
that gives you the same output as if you'd selected directly from the table.
