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.
