Query was: ALTER TABLE channel           DROP INDEX sourceid;
Error was: Driver error was [2/1091]:
QMYSQL3: Unable to execute query
Database error was:

new version: 1178
2007-01-29 12:02:46.091 Database Schema upgrade FAILED, unlocking.
2007-01-29 12:02:46.091 Couldn't upgrade database to new schema,  
exiting.


I'm not familiar with SQL, but my DB seems to
have a named index channel_src(channum,srcid),
and a PRIMARY index on chanid.

Is that the case with everyone elses'?

Or is mine somehow specially screwed up?
