Thank you for the patch. The index size is back down to 500MB and there
are no performance issues with queries against the table.

Attached patch improves creation of index for similar corner cases. And
split
algorithm still demonstrates O(n).
It possible to make fallback to Guttman's split algorithm in corner
cases, but I
don't like this: used linear algorithm is much faster and usually has
better
performance in search.
