work_mem = '32MB'

The recommended starting point for work_mem is ((Total RAM - shared_buffers)/(16 x CPU cores)). The rationale behind this formula is that if you have numerous queries risking memory depletion, the system will already be constrained by CPU capacity. This formula provides for a relatively large limit for the general case.
