"Corrupted" means data loss or integrity failure technically
(although its quite common to hear "corruption" applied
to Berkeley DB with other meanings.)
Is there data loss or integrity failure? Running db_verify
cd /var/lib/rpm
db_verify Packages
against Packages or other "tables" (Berkeley DB calls
"tables" databases) will detect integrity failures.
Data loss can be detected by, say, counting the number
of packages installed like
rpm -qa | wc -l

Hang up how? Can you add -vv to a query? There is also
cd /var/lib/rpm
db_stat -CA # <-- -CA displays all info, -Cl displays lock info
Note that you MUST use db_verify/db_stat for the same version of
Berkeley DB used by RPM. The tools for the same version of Berkeley DB if
internal
to RPM are released with RPM.

An rpmdb is protected by permissions on /var/lib/rpm.
The associated __db* files are created as needed.
I would expect "root" as owner typically, because /var/lib/rpm is
usually writable only by "root", and rpm installs are typically run as "root".
But the openpkg wrapper appears to have a different ownership model.

Identifying what is causing the "hang" is what is needed first.
