If you want the gory details, check out the mmgr README file. http://developer.postgresql.org/cvsweb.cgi/pgsql/src/backend/utils/mmgr/README?rev=1.9 However, except in fairly special circumstances (eg. index comparison functions) you don't ever need to bother with pfree(). The memory will all be freed at the right time. The documentation on C functions and set-returning functions also has info about when the context is reset.
