Looking back over the thread, it seems that the problems you saw could
be explained by the VACUUM-related bugs we fixed in 8.1.9 and 8.1.10;
although obviously this theory requires assuming that the dups were
there before you updated to 8.1.11. You didn't say much about time
frame so I don't know if that's plausible.

This latest bit with many fewer index entries than table entries is just
weird, though. The 8.1.10 VACUUM bug could have led to having *more*
index entries than table entries, but not the other way around.

Before you zap the database, would you be willing to make the actual
database files (not a dump, but the stored files) available? I'd
be interested to take a closer look at that index.
