Deletion of Posts - triggers and hooks

[ykkrox]

This forum is really helpful! Now I got some more questions to post.

So now I've created a new plugin, I wanted to be able to detect a post being deleted by a Moderator or Admin.

What hook should I use to detect this action so that I can update the database to reflect the changes right away?

Of course there is a 'soft' delete and a 'physically remove', is there an array that contains either value? A sort of deletion array?

Thanks as always!
