* Each index key can have lower and/or upper bound. Setting the key
* equal to a value defines both upper and lower bounds. The bounds
* can be defined in any order. Conflicting definitions is an error.
*
* For equality, it is better to use BoundEQ instead of the equivalent
* pair of BoundLE and BoundGE. This is especially true when table
* distribution key is an initial part of the index key.
*
* The bounds must specify a single range i.e. they are on an initial
* sequence of index keys and the condition is equality for all but
* (at most) the last key which has a lower and/or upper bound.
* The sets of lower and upper bounds must be on initial sequences of
* index keys. All but possibly the last bound must be non-strict.
* So "a >= 2 and b > 3" is ok but "a > 2 and b >= 3" is not.
*
* The scan may currently return tuples for which the bounds are not
* satisfied. For example, "a <= 2 and b <= 3" scans the index up to
* (a=2, b=3) but also returns any (a=1, b=4).
*
* NULL is treated like a normal value which is less than any not-NULL
* value and equal to another NULL value. To search for NULL use
* value and equal to another NULL value. To compare against NULL use
* setBound with null pointer (0).
*
* An index stores also all-NULL keys (this may become optional).
* Doing index scan with empty bound set returns all table tuples.
