> eventual removal
To me, the idea that the deletion takes time to complete doesn't negate the idea that the data will be gone once the process completes.
WAL archive and backups are external systems. You could argue that nothing supports deletion because an external backup could exist, but that's not a useful conversation.
Going back to the point of the the thread, we agree the deleted data is not erased. The user is unable to access it through normal mechanisms, but the existence of side channels that could reveal it does not negate the idea that it has truly been “deleted”, especially when one looks at the historical context surrounding that word.
What? I don't agree with that.
Can you point to an example of a modern database that "supports deletion" but keeps the data around forever? Maybe I've just used different tools than you. Knowing modern data retention concerns I'd be surprised if such a thing existed.
Who said anything about that? We’re talking about side channels and eventual^TM deletion. Given enough time no information will remain anywhere, sure. But that’s not very relevant.
