The zombies couldn't be dead backends if the postmaster has gone away:
in every Unix I know, a zombie process disappears instantly if its
parent dies (since the only reason for a zombie in the first place
is to hold the process' exit status until the parent reads it with
wait()).

Find out what the parent process of the zombies actually is.
