That's true, but are you actually arguing for keeping work_mem at 1MB?
Even on a VM with only 1GB of RAM, work_mem=4MB is not going to cause
any problems unless you're also trying to service a large number of
simultaneous connections. And if you're doing that, you probably need
to rethink something anyway.
