Introduces BeginCopyFrom_compat macro 

BeginCopyFrom function now has a new whereClause parameter.
In the function this parameter is assigned to the whereClause field of the CopyFromState returned
Currently in Postgres there is only one place where this argument isn't NULL, and in previous PG version the whereClause argument of copy state is set right after the function call
Since we don't have such example all current whereClause parameters are set to NULL
