It's not on the radar at the moment.  If this standard gets any
real uptake (too soon to tell), somebody might build an extension
datatype that works with it.

AFAICT from a quick read of 9557, the intent is precisely to represent
*more* information than just a point in time, or even just a point in
time and an intended timezone.  So IMO it wouldn't make any sense for
the built-in timestamptz type to deal with this.  Yeah we could make
timestamptz_in read this format, but it'd be throwing away all of the
additional information over an RFC 3339 timestamp, which seems like
not the right thing.
