Log Message:
-----------
RecentXmin is too recent to use as the cutoff point for accessing
pg_subtrans --- what we need is the oldest xmin of any snapshot in use
in the current top transaction.  Introduce a new variable TransactionXmin
to play this role.  Fixes intermittent regression failure reported by
Neil Conway.
