Maybe related question: is the code below in XactLockTableWait() related to
SIGQUIT?

 /*
  * Transaction was committed/aborted/crashed - we have to update pg_clog
  * if transaction is still marked as running.
  */
 if (!TransactionIdDidCommit(xid) && !TransactionIdDidAbort(xid))
  TransactionIdAbort(xid);

I interpret that if a quickdie or crash happens, then other backends may
still run for a while, so it is important to mark related transaction abort.
Or there is some other more obvious reason for that?
