I ended up pushing a slightly revised version of this which kept the
code the same as before when rs_numblocks had not been changed. I
backpatched to 9.5 as it seemed low risk and worthy of stopping some
head-scratching and a future report for any extension authors that
make use of heap_setscanlimits() with backwards scans at some point in
the future.
