Not sure -- sheer luck ;-)

Probably TopMemoryContext
"TopMemoryContext --- this is the actual top level of the context tree;
every other context is a direct or indirect child of this one.
Allocating here is essentially the same as "malloc", because this
context will never be reset or deleted."
I.e. anything allocated in TopMemoryContext will live until the session
ends.
See:
http://www.joeconway.com/tut_oscon_2004.pdf
particularly starting at or about page 64. Much of the detailed
explanation is not in the slides, but it should give you some examples
and ideas. There are examples throughout the presentation, and several
of them have examples of memory context use.
