field name or index with bad_result_process error

[neel]

In a complected select query, An error message like the following makes it very hard to understand which field has a wrong type. And it takes time to find out the one which is wrong.

unexpected oid 19 for type long: no conversion possible from oid to user-supplied type

Is it possible to to have the field name or at least the field index attached with the error message ?

Hi Neel.

Well, for the moment to get the field name it is possible to receive ozo::result (see result integration test for the details and then apply ozo::recv for a column value in a row to determine which one contains data type with an inappropriate OID. But with a composite type, unfortunately, there is no such mechanism to get rich debug information about the problem, since no stack-like context is provided for the deserialization functions.

This situation is not convenient and should be improved for sure. So any help here is welcome.
