Swap as in RAM swap space? If so, then it uses as much or as little as
Linux thinks needs to be used, given the amount of RAM.
effective_cache_size, work_mem, shared_buffers,
maintenance_work_mem, max_worker_* and max_parallel_* affect how much RAM
PG uses, in conjunction with the number of active connections (including
maintenance work).
https://postgresqlco.nf/doc/en/param/ is a handy resource.
