Summary: SQLStatistics returns UNKNOWN instead of real column names

Initial Comment:
Created By:     den <NOSPAM> intech.ru
Description:

    STEPS TO REPRODUCE
    1. CREATE TABLE temp_table (a int)
    2. ALTER TABLE temp_table DROP COLUMN a
    3. ALTER TABLE temp_table ADD COLUMN a int
    4. CREATE INDEX temp_index ON temp_table (a)

    CAUSE OF FAILURE
    Source code has a petty hole based on the erroneous interpretation of the
    column index stored in the pg_index.indkey. In this case the column index is
    not a sequence number of column, but value of the pg_attribute.attnum.

    Listing of source code: info.c (psqlodbc-08.00.0102)
    ....
    2824 if (fields_vector[i] == OID_ATTNUM)
    2825 {
    2826 set_tuplefield_string(&row->tuple[8], "oid");
    2827 mylog("%s: column name = oid\n", func);
    2828 }
    ->2829 else if (fields_vector[i] < 0 || fields_vector[i] > total_columns)
    2830 {
    2831 set_tuplefield_string(&row->tuple[8], "UNKNOWN");
    2832 mylog("%s: column name = UNKNOWN\n", func);
    2833 }
    2834 else
    2835 {
    ->2836 set_tuplefield_string(&row->tuple[8],
    column_names[fields_vector[i] - 1]);
    2837 mylog("%s: column name = '%s'\n", func,
    column_names[fields_vector[i] - 1]);
    2838 }
    ...

Please try the experimental version.
Please download it from this page and replace
 the dll(psqlodbc35w.dll) by the one at

.
