[CC any replies, thanks]
This is basically a refined version of the last one.
- It restricts itself to btree indexes
- Doesn't play tricks with RestrictInfos and focuses on a new type
of ScanKey. Thus, the EXPLAIN output looks correct now also.
- Does IS NOT NULL as well as IS NULL
- Probably better use of statistics.
It's messier because now more places need to know about it, but
functionalitywise it's like the last one.
