Alvaro Herrera de887cc8af Avoid hot standby cancels from VAC FREEZE 
VACUUM FREEZE generated false cancelations of standby queries on an
otherwise idle master. Caused by an off-by-one error on cutoff_xid
which goes back to original commit.

Analysis and report by Marco Nenciarini

Bug fix by Simon Riggs

This is a correct backpatch of commit 66fbcb0d2e to branches 9.1 through
9.4.  That commit was backpatched to 9.0 originally, but it was
immediately reverted in 9.0-9.4 because it didn't compile.
