You don't say what language you want to use, but assuming it's plpgsql, 
then for the simple case you can just do:

LOOP  INSERT INTO mytable VALUES (var1, var2);
END LOOP

Now, let's say you wanted to change mytable as well as the values, you'd use  sql := ''INSERT INTO '' ||
quote_ident(my_table_variable)|| '' 
 
VALUES  ...etc'';  EXECUTE sql;

Does that help?
