Summary: Bug in PGAPI_ExtendedFetch()

Initial Comment:
PostgreSQL 8.3.3
PostgreSQl ODBC Driver 08.03.0200

IMHO is an bug within the function PGAPI_ExtendedFetch() (file result.c). This error is occur when query a rowset with number of n rows (n >1) and SQL_ATTR_ROW_ARRAY_SIZE is greater than 1 an less than n (in second and subsequent calls of PGAPI_ExtendedFetch() via SQLFetch()/ SQLFetchScroll()).

starting with the line 1482

    switch (fFetchType)

                SC_inc_rowset_start(stmt, progress_size); <-- line 1515

should be changed to
                SC_inc_rowset_start(stmt, stmt->last_fetch_count); 

because the offset to determine the following rows depends on the number of previously retrieved rows, but not on the number of lines requested.

best regards
