Rebuild .deb packages database

[zmdmw52]

Is there a command (from the CLI) to rebuild the package database in Ubuntu - similar to the rpmdb --rebuilddb / rpm --rebuilddb for RPM-based systems (Fedora/openSUSE), as mentioned here (http://linuxpoison.blogspot.com/2007/10/repair-corrupt-rpm-database.html):

or for openSUSE at this link (http://en.opensuse.org/SDB:Speed_up_Package_Manager_Stack#Defragment_inte rnally):

First backup and then delete by doing the following command:
$ su
# cp /var/lib/rpm/__db.001 /home/nikesh
# rm /var/lib/rpm/__db.001
# cp /var/lib/rpm/__db.002 /home/nikesh
# rm /var/lib/rpm/ __db.002

# rpm –rebuilddb
