and the literal syntax INTERVAL 'string' ... SECOND(n), as required by the SQL standard. Our old syntax put (n) directly after INTERVAL, which was a mistake, but will still be accepted for backward compatibility as well as symmetry with the TIMESTAMP cases. Change intervaltypmodout to show it in the spec's way, too. (This could potentially affect clients, if there are any that analyze the typmod of an INTERVAL in any detail.) Also fix interval input to handle 'min:sec.frac' properly; I had overlooked this case in my previous patch. Document the use of the interval fields qualifier, which up to now we had never mentioned in the docs. (I think the omission was intentional because it didn't work per spec; but it does now, or at least close enough to be credible.) |
