That is not a PostgreSQL process.
It looks very much like malware running on your system, that happens
to be running under the "postgres" user account.
I'd shut the machine down immediately. And then mount the file system
through some other means (meaning mount the disk from a different
system and absolutely do *NOT* boot off this disk), figuring out where
those binaries are and try to salvage the database from there.
