Exclude VACUUMs from RunningXactData
GetRunningTransactionData() should ignore VACUUM procs because in some
cases they are assigned xids. This could lead to holding back xmin via
the route of passing the xid to standby and then having that hold back
xmin on master via feedback.
Backpatch to 9.1 needed, but will only do so on supported versions.
Backpatch once proven on the buildfarm.
