Won'tthat kind of difference matter when you want to apply the changes to your production database?
Yikes! That could be bad. Drop column xyz. Hope that data wasn't
important. To see if the column was renamed or something you'd have
to examine its rows to see if they matched a previous version.
I think that at the least I'd trawl the logs with ddl logging turned
on to get changes. But seriously, I'd just lay down the law. You
want changes in the dbs outside development, you give me, the DBA,
your DDL statements. No statements, no code push.
