It is in info.c, SQLStatistics():
               /*                * Clustered index?  I think non-clustered should be type                * OTHER not
HASHED               */               set_tuplefield_int2(&row->tuple[6], (Int2) (atoi(isclustered) ?
SQL_INDEX_CLUSTERED: SQL_INDEX_OTHER));
 

The HASH mention has me confused.  Is that code valid?  Maybe so.  What
does ODBC think the column means, HASH or CLUSTER?
