But it's hot standby, so there are no data-modifying transactions.
Volatile functions could be a problem, though. A bigger problem is
we might have already shipped partial query results to the client.
I agree it ain't easy, but it might not be completely out of the
question. Definitely won't be happening for 9.0 though.
