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. -- Death to <Redacted>, and butter sauce.
