In any case the tuple will probably "jerk around" different pages (I
don't think it's different whether the pages are from two tables or from
the same one). I fail to understand how that is a different performance
problem than for any other datatype. I'm sure you've done some
benchmark to determine that the varchar handling is as slow as you
appear to be saying?
