IIRC the end conclusion on that patch was that it was awfully messy,
didn't really buy much in new functionality, and was trying to track a
portion of the spec that the SQL committee had apparently not gotten
right yet.

Implementing stuff that's still changing in a *draft* standard seems
to me like a good way to get burnt.
I think this needs to stay on the back burner, at least until there's
a published final spec that doesn't seem as broken as 2003 was. I
was sufficiently disillusioned with the whole thing at the end of
the previous review cycle

that I'm not really eager to pour more time down the same hole.
