Perhaps you can try reducing the shared_buffers, to see if that helps
more? 8MB is quite small for workmem. More shared_buffers is not
necessarily better.
Also, how much swap are you running? overcommit disabled while not
having any swap setup is a great way to ensure you run out of memory
quickly.
Have a nice day,
