Re: Things I don't like about \du's "Attributes" column

 

Would it make sense to make the column non-nullable and always set it to infinity when there is no expiry?

In this case, I think NULL simply means infinity, so why not write that? If the timestamp type didn't have infinity, then NULL would be a natural way of saying that there is no expiry, but with infinity as a possible value, I don't see any reason to think of no expiry as being the absence of an expiry time rather than an infinite expiry time.
