TransactionIdIsInProgress() doesn't consult the known-assigned-xids
structure. That's a problem: in the standby, TransactionIdIsInProgress()
can return false for a transaction that is still running in the master.
HeapTupleSatisfies* functions can incorrectly set HEAP_XMIN/XMAX_INVALID
hint bits for xids that commit later on.
