I use loops like this (there are more ways, but I think what you're doing is wrong):
FOR row IN (query) LOOP END LOOP; Where "row" is a variable of type RECORD. I'm not sure how this works with CURSOR, or if postgres 7.4 has different loop constructs, but you might want to look into that, in the documentation. It has a section on loops for plpgsql.
