The loop variable has to be a record or row variable, not an integer.

FWIW, 7.5 will give a better error message for this common mistake.
In CVS tip I get

ERROR: loop variable of loop over rows must be a record or row variable at or near "LOOP" at character 416
LINE 14: FOR actual IN EXECUTE v_query LOOP
