There is no way to record queries and shut down the server at the same time.
That's like saying I want to shut off my car engine but keep driving.
I believe you are looking at the wrong solution.
The best way to migrate and keep all transactions is to use Slony replication.

You can start the migration to the new server and when it's finished, you
simply failover to the slave and redirect the url to it.
