After digging into this a little more, I discovered that the root cause of this is actually in the PostgreSQL JDBC driver which includes the query parameters in a batch query exception. https://github.com/pgjdbc/pgjdbc/blob/0888e9355ca065ac2eae4e3085442ffd54f6dec6/pgjdbc/src/main/java/org/postgresql/jdbc/BatchResultHandler.java#L145

I apologize for not discovering that in the first place and would like to withdraw this issue.
