Hello Bruce,

Here is some, for things I know about:

>> Add major scripting features to pgbench (Fabien Coelho)

I assume that you are refering to "bc7fa0c1". I do not think that anything 
qualifies as "major".

I would rather describe it as "Add support for NULL and boolean, as well 
as assorted operators and functions, to pgbench expressions". Or something 
in better English.

>> Add \if macro support to pgbench (Fabien Coelho)

I would remove the word "macro", as it is not a pre-compilation feature, 
it is just a somehow simple standard conditional.

I'm planning to try to help with the later.
