which is in Debian base system, and maintainers are allowed to use them.
A quick grepping through postinst gives me:

iptables.postinst:if [ "$1" = configure ] && which install-docs >/dev/null 2>&1; then
fdutils.postinst:if [ "$1" = configure ] && which install-docs >/dev/null 2>&1; then
man-db.postinst:if [ "$1" = configure ] && which install-docs >/dev/null 2>&1; then
