sorry, i don't quite follow what you're saying here. we changed the view
definitions on the toolserver when rev_deleted went into use to avoid exposing
this information to the users. we don't use any sort of trigger.
BTW: there is no "partial replication" at the toolserver, although this is a
common misconception. we replicate everything, then use views to expose the
relevant data to users. this is why the foundation won't allow us to add any
more admins; the internal / private wikis are also replicated to the
toolserver, and visible to any admin.
I know. That's precisely what i'm addressing. From your email, WMF is
"reorganising their databases" so the toolserver can get more admins
(less private data is replicated/stored at ts).
Any such schema change to the schema would be pretty big, IMHO (and yet
incomplete).
Moreover, any
more private method for sharing the tables (eg. a trigger
deleting the row when rev_deleted is set) would precisely lose the backup
ability the toolserver is performing.
i don't know what you mean by "more private", but the method we use has no
effect at all on how useful the toolserver would be as a backup.

Changes so toolserver roots can't get /some/ information would.
