As you can see in the manual (http://www.postgresql.org/docs/8.1/interactive/plpgsql-control-structures.html) you have to remove the ; after the initial LOOP
 
LOOP
    statements
    IF i > 1000000 THEN EXIT;
END LOOP;
 
Or you can try...
 
WHILE i <= 1000000 LOOP
    statements
END LOOP;
 
Or even... (don't initialize i in this case)
 
FOR i IN 1 .. 1000000 LOOP
    statements
END LOOP;

I tryed a way but it is not working. Please see it:

LOOP;
    -- some computations
insert into carga (desc) values ('My Text');
    IF count > 1000000 THEN
        EXIT;  -- exit loop
    END IF;
END LOOP;

The postgresql reports the following error:
/
ERROR: syntax error at or near "LOOP"
SQL state: 42601
Character: 1/
