Since in float8 you can use '+inf', '+infinity', So should we also make interval '+infinity' valid? Also in timestamp. '+infinity'::timestamp is invalid, should we make it valid. In float8, select float8 'inf' / float8 'inf' return NaN. Now in your patch select interval 'infinity' / float8 'infinity'; returns infinity. I am not sure it's right. I found this related post ( https://math.stackexchange.com/questions/181304/what-is-infinity-divided-by-infinity ). I recommend David Deutsch's <<The Beginning of Infinity>> Jian
