I've got this little script:

iam="${0##*/}"
match="${1}"
ex=0
declare -A pkg_local
pkg_local_dir="/var/lib/pacman/local"
pkg=""
_pkg=""
pkg_name=""
pkg_entry=""

for pkg in "${pkg_local_dir}"/*
do
    _pkg="${pkg##*/}"
    pkg_name="${_pkg%-*-*}"
    pkg_entry=${pkg_local["${pkg_name}"]}
    [ -z "${pkg_entry}" ] && {
        pkg_local["${pkg_name}"]="${_pkg}"
        :
    } || {
        pkg_local["${pkg_name}"]="${pkg_entry} ${_pkg}"
        echo "${iam}: duplicate: ${pkg_local[${pkg_name}]}"
        ((ex++))
        :
    }
done

shopt -s extglob

[ -n "${match}" ] &&
for pkg in "${!pkg_local[@]}"
do
    pkg_entry=${pkg_local["${pkg}"]}
    [ -z "${pkg}" ] && {
        echo "${iam}: zero entry: ${pkg} -> ${pkg_entry}"
        ((ex++))
        continue
    }
    case "${pkg}" in
        ${match})
            echo "${iam}: match: ${pkg} -> ${pkg_entry}"
            ;;
    esac
    case "${pkg_entry}" in
        ${match})
            echo "${iam}: match: ${pkg} <- ${pkg_entry}"
            ;;
    esac
done

exit ${ex}
