Please add a test that verifies a case when client uses different bind types for "the same" statement.

For example:

```java
String sql = "select * from inttable where a = ?;select * from inttable where a = ?;select * from inttable where a = ?";
...
ps.setInt(1, 42); ps.setString(2, "43"); ps.setDouble(3, 44.0);
```

The execution plan might depend on the result shape, so we can't easily reuse server-side handles by looking at the SQL alone.

We might be looking at https://github.com/pgjdbc/pgjdbc/issues/345
