If you include the parent process id in the "ps" output, and run "postfix
status", you'll see which master(8) process is which instance, and thus
which instance owns which sub-process. Sadly "postfix status" never sends
anything to pipes, it just syslogs when the output is not a terminal...
So to find which master is which instance you need to look in the master.pid
files or in /proc, ... If you do look in /proc, each child process has
MAIL_CONFIG in its environment...
