v1-0001-Add-Boolean-node.patch (text/plain) patch v1-0001

This patch adds a new node type Boolean, to go alongside the "value" 
nodes Integer, Float, String, etc.  This seems appropriate given that 
Boolean values are a fundamental part of the system and are used a lot.

Before, SQL-level Boolean constants were represented by a string with
a cast, and internal Boolean values in DDL commands were usually 
represented by Integer nodes.  This takes the place of both of these 
uses, making the intent clearer and having some amount of type safety.
