Deleting permanently data from WordPress

Is it possible to delete certain spacific information in WordPress DB without having to go to the DB table?

Type:
– I permanently deleted certain image (name.jpg) and then resubmitted with the same name – WP will insert as name-2.jpg
– I deleted a user with the email [email protected]; if I decide to add the user again with this email WP will not let me.
Is there a plugin to make permanent deletions in the WP DB? I didn’t want to have to use plugins to scan all “deleted” records in BD, as this implies doing and restoring bkp from BD (which can be problematic).
