Of course, an index has its own B-Tree, plus a full copy of the indexed data. This is likely to add much more overhead than you'll gain back by merging a few tables. Personally I don't think the overhead described is out of line, especially if none of the user columns are marked INTEGER PRIMARY KEY. -j -- Jay A.
