Agreed, but if anyone has a table with close to 1600 columns in a
table... is either nuts or knows what they're doing. If someone has
>1600 columns, that is an issue, but isn't one that I think can be
easily fended off without the backend being able to adapt on the fly
to different block sizes, which seems like something that could be
done with a rewrite of some of this code when table spaces are
introduced.
