Just to explain this a little further: Effectively the code thought
"IS NOT TRUE" meant "IS FALSE", and "IS NOT FALSE" meant "IS TRUE".
That was wrong because each of the NOT cases should have allowed
NULLs.
Maybe the wording can be adjusted to mention NULLs. Maybe something
along the lines of:
* Fix partition pruning bug with the boolean "IS NOT TRUE" and "IS NOT
FALSE" conditions. NULL partitions were accidentally pruned when they
shouldn't have been.
