Ok, so the interpretation of this field is:
A match in the index needs to be reevaluated in the heap tuple data,
since a match in the index does not necessarily mean, that the heap tuple
matches.
If the heap tuple data matches, the index must always match.
A very typical example for such an index is a hash index. This might explain the
fact, that the ODBC driver misinterpreted that field as meaning that the index is a
hash.
The field has nothing to do with partial index.
