These look very approximate.

That's not a bad recommendation, but not an actual requirement.   It really 
depends on how much sort_mem you need.   Could vary from 0.5mb to as much 
as 256mb per connection, depending on your application.

Well, my compiled source takes up 87mb, and the installed PostgreSQL seems 
to be about 41mb including WAL.  Not sure how much the regression tests 
are.
