Volodymyr Vysotskyi updated CALCITE-2253:
-----------------------------------------
Description:
In CALCITE-2206 was prevented pushing windowed aggregates down for the
{{SqlDialect}} s which do not support windowed functions.
After these changes, {{JdbcProjectRule}} is matched *only* for the cases when
{{SqlDialect}} supports windowed functions and project contains windowed
functions:
{code:java}
return out.dialect.supportsWindowFunctions()
&& !RexOver.containsOver(project.getProjects(), null);
{code}
