random thoughts, may or may not be useful:

        pkg_info -V

        test -e ${PKG_DBDIR}/pkgdb.byfile.db

        test -d ${PKG_DBDIR}/../pkg.refcount

        test -d ${PKG_DBDIR}/digest-*

        test -e ${PKG_DBDIR}/digest-*/+SIZE_ALL

        test -e ${PKG_DBDIR}/digest-*/+BUILD_INFO

        test -e ${PKG_DBDIR}/digest-*/+BUILD_VERSION
