   Can someone add a link to where this potential issue was reported please.
   
   I agree with Andrija, this is a scary message that basically says: upgrading may or may not trash your database, and that the Admin needs to check their schema, looking for a non-specific problem, and then apply a non-specific fix.
   
   If there _is_ an issue, it's our job to ensure that the MySQL upgrade statements work, not the end-users.  
   
   Worst case, we should check that the schema changes are applied correctly as we go (not a bad idea to do this as a standard procedure for all schema updates).  We can then retry with the alternate syntax, or just fail fast.
