the only way to execute a rule is to fire it (i.e., by running a
query that matches the condition under which it is supposed to be
triggered).

if two rules are defined in such a way that you cannot formulate a
query that does not trigger one without triggered the other, then you
lose.  there is no way to turn off rules temporarily (though you can
remove them, of course).
