This is RFC because I'm unhappy with the current names, but they are 
going to be bikesheded anyway. So I would like to get the topic moving 
and code is a good way to get that.

The name in this series are:

- txnopen (can abort)
- txnclosing (can abort)
- txnclosed

The name that would fit existing hooks best will probably be:

- pretxnopen (can abort)
- pretxnclose (can abort)
- txnclose

However, I always struggle to find out which of the hook can actually 
abort a transaction. so I like the "closed" version that settle this down.

So current optimal idea is probably:

- pretxnopen
- pretxnclose
- txnclosed

But I've also to admit that "txn" is not the most sexy thing we have 
ever done.

Though?
