So are you voting against adding any attribute-ID info to
RowDescription? While I'm not that thrilled with it myself, it seems
relatively harmless as long as we can keep the overhead down. I'm
okay with attrelid/attnum, but would gripe about including more than that.
You're probably right that updatable cursors would be a nicer solution
in the long run, but I don't really see that happening in the next
release or two.
