What error message do you get if setting shared_buffers higher than 1GB?
Exactly what error message do you get when the application crashes?

That's way too high for most applications. In a complex query, each sort
or hash node can will use up work_mem amount of memory. That means that
if you have a very complex query with several such nodes, it will run
out of memory. Try something like 16MB.
