test=> select * from test;
d

(1 row)
// this is OK
test=> select date(datetime(d) + '1 month'::timespan) from test;
date
----------
01-06-1998
(1 row)
// this is OK
test=> select date(datetime(d) + '5 months'::timespan) from test;
date
----------
01-10-1998

// Ooops!
test=> select date (datetime(d) + '6 months'::timespan) from test;
date
----------
31-10-1998
