ERROR: control reached end of function without RETURN, except, it is not a function it is a procedure or a nameless block.

[Herwig Goemans <herwig.goemans@xxxxxxxxx>]

Hi Support,


I get an error in a stored procedure - not a stored function mind you - 
control reached end of function without RETURN

The error occurs when doing an exit <label> in  a stored procedure. Now 
I cannot give all of the stored procedures involved but I can simulate 
te problem with a very simple block:



DO
$BODY$
<<simple_block>>
BEGIN
begin
               exit simple_block;
         -- for demo purposes
              raise notice '%', 'unreachable!';
   end;
   raise notice '%', 'End of block';
end;
$BODY$

This will return the error on Postgres version 13, Version 12 and 9.


Now I thought this was text-book behaviour of exiting a code block. I do 
not like programming this way but it is part of a migration project of 
Oracle to PG.

What do I miss ?

Kind regards,


If you put this code snippet in a file and execute like:

postgres@herwig-NUC10i7FNH:~$ psql -f  do_test.sql
psql:do_test.sql:12: ERROR:  control reached end of function without RETURN
CONTEXT:  PL/pgSQL function inline_code_block
