It's not perfect, however:

mkdir emptydir3; cd emptydir3; touch ./-z

Frankly, I think the only reasonable action to consider in a postrm would
be removing the empty directory, in which case just use rmdir on it
[if this is the only command in the postrm, don't bother with set -e,
if it's one of many steps and can only happen after the set -e follow
rmdir with ||true].
