There's a difference between "natural" order (the location in the database
or on disk) and "record" order (the order specified by the primary key)...

SQL only imposes an order on the return set if you add an "ORDER BY"
clause.
You can't expect any particular order to either recur or NOT recur
unless you have specifically requested a particular ordering.
There's no bug; just use ORDER BY if you need to, and, if you don't,
make sure you don't expect any particular ordering...
