It is of course a "bashism" and not a POSIX-shell feature, so you
won't find in /bin/sh on most systems or in /bin/ksh.  It is the
primary reason I use bash as my shell, <(cmd) is just way too
convenient, I use it dozens of times a day.

I don't think that the "comm" or "join" tricks belong in postconf(1)
documentation, but they could be in a Postfix-related Wiki, or
HOWTO document.
