Honestly, I think the main "optimizations" happen automatically: the
compiler uses the extra registers (if present) and pointers in LP64
mode are automatically 64-bit, which allows much larger memory areas.
That's probably 95% of the win right there. What other
"optimizations" need doing?

People have been running PG with big databases on 64-bit iron for
years; don't you think any glaring infelicities would have been
addressed?

What re-architecting would be needed?
