It seems that coalesce function in SQLite loses expression type

So following query does not work

   SELECT order0_.*
   FROM   Orders order0_
   WHERE  COALESCE(order0_.Freight, 0) > @p0;

And a query with cast around coalesce works

   SELECT order0_.*
   FROM   Orders order0_
   WHERE  CAST(COALESCE(order0_.Freight, 0) as NUMERIC) > @p0;
