postgres itself doesn't track that level of OS specific stuff.
Do we have any system tables which can give us the data? I have found
this one
https://aaronparecki.com/2015/02/19/8/monitoring-cpu-memory-usage-from-postgres
but dont know whether it is exactly the same what I need.
thats reading the /proc/.... stuff available on Linux systems via SQL,
its the same stuff OS level tools like ps, top, free use... it won't
work on non-Linux systems, even other Unix systems like BSD don't have
the same /proc stuff, and other OS's like Windows don't have /proc at all.
if you don't know whether that's what you need, I'm not sure how we
could know what you need.
