Tom Lane 6980f817e8 Stop btree indexscans upon reaching nulls in either direction.

The existing scan-direction-sensitive tests were overly complex, and
failed to stop the scan in cases where it's perfectly legitimate to do so.
Per bug #6278 from Maksym Boguk.

Back-patch to 8.3, which is as far back as the patch applies easily.
Doesn't seem worth sweating over a relatively minor performance issue in
8.2 at this late date.  (But note that this was a performance regression
from 8.1 and before, so 8.2 is being left as an outlier.)
