Well, now consider update of 2Gb row!
I worry not due to non-overwriting but about writing
2Gb log record to WAL - we'll not be able to do it, sure.
Isn't it why Informix restrict tuple len to 32k only?
And the same is what Oracle does.
Both of them have ability to use > 1 page for single row,
but they have this restriction anyway.
I don't like _arbitrary_ tuple size.
I vote for some limit. 32K or 64K, at max.
