Alexander Korotkov e3e05addee Fix wrong logic in TransactionIdInRecentPast() 
The TransactionIdInRecentPast() should return false for all the transactions
older than TransamVariables->oldestClogXid.  However, the function contains
a bug in comparison FullTransactionId to TransactionID allowing full
transactions between nextXid - 2^32 and oldestClogXid - 2^31.

This commit fixes TransactionIdInRecentPast() by turning the oldestClogXid into
FullTransactionId first, then performing the comparison.

Backpatch to all supported versions.
