> See the title. Currently, postgresql-style cast has lower operator priority than some operators like equal(=). So, the following statement does not work properly.
> {noformat}
> tajo> select l_shipdate from lineitem where l_shipdate = '1996-03-13'::date limit 1;
> ERROR: No operator matches the given name and argument type(s): lineitem.l_shipdate (DATE(0)) = 1996-03-13
> {noformat}
