No (I mean you can store it in the filesystem or such as well, but
...). Pretty fundamentally sharing data between concurrently running
processes needs a medium to share the data over. The bgw infrastructure
allocates just enough so you can put an index to it into
shmem. Allocating more would be wasteful and/or not enough for some
users.
