Hm. I have to say the single most confusing thing about the Postgres
source that took me a *long* time to get over was remembering that
some of the typedefs were already pointers and some weren't. It seems
silly now but when I was trying to understand what the intent of a
function was and it wasn't obvious that some of the arguments appeared
to be pass by value but were actually pass by reference it made things
really surprising.
