I suppose the "invalid" value is a legacy thing, but "infinity" certainly strikes me as useful. We have that in the regular timestamp type as well. If you're asking why those particular encoded values, I dunno. Certainly it seems like "infinity" needs to be larger than all normal values so you don't have to special-case it in comparisons. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 7: don't forget to increase your free space map settings
