Ah, I have to do

RETURN '___WRONG___';

Not necessarily.

and not

out_text := '___WRONG___'
RETURN;

You must rather end the assignment with a semicolon:

out_text := '___WRONG___';
RETURN;

Otherwise what really happens is:

out_text := '___WRONG___' RETURN;

where „return“ is a simple column name as in this select statement:

select '___WRONG___' return;
