Well, I have to say I've never seen this failure mode. Can you assist
me with debugging it? I don't see anything that gives me a clue about
what part of the postinstall is failing or why.

Yes.
In a chroot, install debfoster, then run:
debfoster -o MaxPriority=required -o UseRecommends=no -f -n apt debfoster

Then:
apt-get install clamav-base

I modified clamav-base to run 'set -x':

Arg. Good catch. I see that for some reason I must have been
mistakenly thinking that the subshell would handle that, but clearly
not. So it should be

newal=`which newaliases || true`.

Will upload soon, and thanks,
