How to remove unused tables in the database in Drupal 7 Is there an easy way to detect tables that are no longer used by my Drupal installation? I find it annoying that tables from previously used modules remain. I'll simply drop them using phpMyAdmin if not, but its a bit of a pain, and involves backing it up for obvious reasons! ;)
I think Schema will tell you that.
If a module leaves tables after uninstall, that's a bug, and you should open an issue.
