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. Greetings, Andres Freund
