Could anyone tell me why the following does not work without a cast?
mm=> select * from test; f|i|a
------+-+---------------------
404.90|1|{0,1,2,3,4,5,6,7,8,9}
(1 row)
mm=> select i from test where f=404.90
mm-> ;
ERROR: Unable to identify an operator '=' for types 'numeric' and 'float8' You will have to retype this query
usingan explicit cast
mm=> select i from test where f::float=404.90;
i
-
1
(1 row)
Shouldn't there be an implicit cast between numeric and float?
