Have you done benchmarks of some simple workloads to verify this doesn't cause
slowdowns (when not using encryption, obviously)? printtup.c is a performance
sensitive portion for simple queries, particularly when they return multiple
columns.

And making tupledescs even wider is likely to have some price, both due to the
increase in memory usage, and due to the lower cache density - and that's code
where we're already hurting noticeably.
