I'm afraid you're mistaken. Logging to /dev/log and similar sockets
is done by the C-library via the syslog(3) API. Postfix has no
control or knowledge of the socket type involved. TCP sockets are
a poor choice, but work if that's how you choose to configure your
syslog server.
Postfix does not (and never did) write to the syslog socket directly.

This is a different kettle of fish, it is an internal Postfix socket
at other end of which is postlog(8) not syslogd(8).
