On my system the lock file mode is 0600, but otherwise looks
normal.

What about the directory permissions? Run as root and post the
output of:
# bash -c "ls -ld /var{,/lib{,/postfix{,/master.lock}}}"
To fix (if not on a system where the package maintainer provides
an incorrect postfix-files file).
# postfix set-permissions
Otherwise, fix by hand as needed. On my (BSD) system, the data
directory hierarchy permissions are:
# bash -c "ls -ld /var{,/db{,/postfix{,/master.lock}}}"

That does not match "permission denied", you'd be told the lock is
already taken instead.
