Maybe something like:

* Reduce palloc() memory overhead for all memory allocations down to 8
bytes on all platforms. (Andres Freund, David Rowley)

This allows more efficient use of memory and is especially useful in
queries which perform operations (such as sorting or hashing) that
require more than work_mem.
