[mythtv-users] cannot restore database

[UB40D]

There was a power cut at home while I was at work. I came back, restarted
the myth box and the frontend showed a white screen. Attempting to restart
frontend and/or backend didn't work. Neither did rebooting the machine
again. So I decided to restore the latest backup (I have a daily backup
from a cron job.) However, when I run the restore command, it gets stuck at
"dropping database", which shouldn't be the most time-consuming action.

What should I do?
I have tried running the below both before and after a
  sudo service mythtv-backend stop
but it made no difference.

mythconverg_restore.pl --drop_database --create_database --verbose
--filename  mythconverg-1317-20150220033002.sql.gz
