Alexander Korotkov 6897f0ec02 Optimize memory access in GetRunningTransactionData() ...

e85662df44 made GetRunningTransactionData() calculate the oldest running
transaction id within the current database.  This commit optimized this
calculation by performing a cheap transaction id comparison before fetching
the process database id, while the latter could cause extra cache misses.
