No, that's not possible per definition

And BTW there are no postexec hooks as I can see, is that correct?

prompt hooks can be interpreted as "postexec" hooks

Thanks, I know that's prompt_command hook but that's not what I desired.
I just want to know if there's a way to display the current running process id on the title bar.
May be I should go parsing ps's output for now.
Thanks again for your cooperation.
