comment for TwoPhaseGetOldestXidInCommit

Amit and all,

I noticed today that TwoPhaseGetOldestXidInCommit has a header comment
where the same function is called TwoPhaseGetXidByLockingProc:

/*
* TwoPhaseGetXidByLockingProc
* Return the oldest transaction ID from prepared
transactions that are
* currently in the commit critical section.
*
* This function only considers transactions in the currently connected
* database. If no matching transactions are found, it returns
* InvalidTransactionId.
*/
TransactionId
TwoPhaseGetOldestXidInCommit(void)

This inconsistency should be corrected.

Thanks,
