This just shows a bunch of hungry postgres processes (see below).
In response to your slightly-earlier email, swap_enabled is set (its
default) and

A process has specific flag P_INMEM that is normally 1
Also worth noting is that likely candidates for such pageouts include
long-lived daemons that are only needed, or which only need certain pages,
during startup/shutdown. So evicting only those pages to swap allows
optimal use of memory that would otherwise be wasted unnecessarily.

Kernel may decide to swap out entire processes if vm.swap_enabled=1 (default)
and its free page pool heavily stressed or system was configured

Is there a method to determine
Swapping whole processes out is not really a thing any more. Individual
pages are paged to/from memory; if a memory page has no backing file, it
will be allocated a block in swap space as its backing storage.

wasn't even
Hi all,
I've got an amd64 system running 11.1-STABLE r325027, with something
like 20G of swap. "swapinfo" shows that half the swap is used.
So of course I'm curious to know which processes have been swapped
out. I'm not using any "tmpfs" filesystems; no ZFS, no huge amounts of
wired-down memory.
