Putting memory pages to swap is the decision of the linux virtual memory manager not postgres. If your db machine is swapping, first make sure you have set sensible values for the ram related settings like shared_buffers (25%), effective_cache_size (75%) and work_mem (keep it modest at 4 to 16 MB).

hello,
Can someone point me to any doc describing why and how much space postgres uses on the swap of a debian machine ?
it's an old postgres 10, because it is used by a product for which only this version is certified.
(no comment on that, please)
