Steps to reproduce

• Have an optional boolean column for a table
• Write false == x.OptionalBoolean.HasValue on the C# side

The issue

I would expect that to be translated to:

false = (optional_boolean IS NOT NULL)

instead it's translated to:

false = optional_boolean IS NOT NULL

which is interpreted as:

(false = optional_boolean) IS NOT NULL

which always yields true.
