Yes, I saw some docs that hinted as much. I'm still not clear on exactly
what interval_type is supposed to represent, or at least how it would ever
apply to a Postgres attribute. It almost seems as though the spec is calling
for interval_type of 'HOURS' and interval_precision of '2' for an example
interval of '2 hours'? I'd normally say that we should leave it as NULL in
such a case, but someone added a "FIXME" at some point, which led me to
ask exactly what should go in there. Not a big deal, I suppose - it looks
as though few, if any, other products are using those fields either.
Thanks for the reply.
