My expectation is that null Boolean values display as null rather than false. When I issue the same query with-in psql the null boolean values correctly display as NULL.

I don't know if these direction are redundant to what is already provided in the ODBC provider. Perhaps the operator that I've created is causing the problem I am seeing.

Using inttobool(int, bool) defined in the above URL, I see the
following.

xxxxx=> select inttobool(NULL, true);
inttobool
-----------
f
(1 row)

xxxxx=> select inttobool(NULL, false);
inttobool
-----------
f
(1 row)

Is it what you expected ?
