class RewriteBooleans extends Phase

For SQL back-ends which do not support real boolean types for fields and general expressions but which do have special boolean expressions and operators, this phase injects conversions between fake and real boolean values.

The default for booleans in the AST is to use the fake type (mapped to a numeric type by the profile). There are specific places where a real boolean (that can be used in boolean expressions) is required or produced, so we inject a call to ToRealBoolean or ToFakeBoolean as needed.
