Description: Documentation makes inappropriate reference to boolean
logic
Details:

Documentation section 9.1 reads:

"SQL uses a three-valued Boolean logic..."

A "Boolean logic" is a specific thing, and all Boolean logics have 2^k
values; a 3-valued logic is not Boolean. Should read:

"The SQL Boolean type uses a three-valued logic..."

(Curiously, SQL99 appears to be an actual 4-valued Boolean logic)

Attached patch applied to HEAD and 9.0.X.
