I think you actually need to go read that document.

6.6 Details of configuration
When we configure a package (this happens with dpkg --install and dpkg
--configure), we first update any conffiles and then call:
postinst configure most-recently-configured-version
No attempt is made to unwind after errors during configuration.
If there is no most recently configured version dpkg will pass a null
argument; older versions of dpkg may pass <unknown> (including the
angle brackets) in this case. Even older ones do not pass a second
argument at all, under any circumstances.

See the bit about older versions of dpkg?

This is an excerpt from one of my postinst files, so it is
loosely derived from the scripts written by Charles Briscoe-Smith,
March-June 1998.

It is. Why don't you try reading it more carefully?

No, whoever wrote this code (yours truly) actually read
policy, and is trying to hand craft packages that follow it.
