<p style='margin-top:0;margin-bottom:10px;'>We have a few test failures on Postgres Plus 9.2 due to a ambiguous column reference, in these tests:<br/>

<p style='margin-top:0;margin-bottom:10px;'>the problem is in the generated query:</p>

<p style='margin-top:0;margin-bottom:10px;'>there is also comparison failure in <b>testNoArgFcnAndColumnSameNameAsNoArgFunctionHQL</b>, which I belive is caused by the same problem</p>
