Rewrite a single Node.
Rewrite a single Node. This method can be overridden in subclasses to change the situations in which conversions are applied.
Create a conversion to a fake boolean, cancelling out an existing conversion to a real boolean.
Create a conversion to a real boolean, cancelling out an existing conversion to a fake boolean.
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. There are specific places where a real boolean is required or produced, so we inject a call to ToRealBoolean or ToFakeBoolean as needed.
