Database schema differences

Hi, we have upgraded a tracker instance from 2.28 to 2.33 over the past week. I have begun a schema comparison to confirm that all has gone well and have noticed the following tables in our production DB that are not present in a fresh 2.33.4 installation:

program_criteria
userroledataset
validationcriteria

I see userroledataset is mentioned in upgrade-229.sql, so it was there in 2.29 but I don’t see the other two mentioned at all in the upgrade scripts from 2.28 so I’m a bit baffled as to why they’re not present in 2.33.4 but not dropped in any of the upgrade scripts.

If anyone can shed some light, I’d appreciate it!
Thanks
Ed
