Hey
After upgrading Firebird provider from 4.7.0 to 5.1.1 I receive the following exception: "FbParameterCollection already contains FbParameter with ParameterName 'id'." when executing the following update or insert statement(the statement have been simplified).

UPDATE OR INSERT INTO TESTTABLE (id)
VALUES (@id)
matching (id)
returning id

The statement is executed with a input parameter named "@id" and a output variable named "id".

On the project i work on this pattern is used many times, is there a chance that this change can be reverted?
