Quanah,

Thanks for the comment about the move from Hash to Btree indices, as well
as your performance metrics.  I wonder what the reasoning was for doing
this.  Developers, any answers on this?

If you want to re-enable the Hash indexing, it looks like if you add
-DBDB_INDEX_USE_HASH  to your CFLAGS, it will set it back to using the
Hash based method.  FYI.

The reason was to improve indexing performance, which Btree definitely does. ;)
