On Toolforge, I am unable to access the page table for the dewiki_p database using the stimmberechtigung account:
[dewiki_p]> DESCRIBE page; ERROR 1356 (HY000): View 'dewiki_p.page' references invalid table(s) or column(s) or function(s) or definer/invoker of view lack rights to use them
The same query does work for enwiki.
