Here is a test case that crashes even with the patch:
I was too optimistic :(
Attached patch contains:
- changes in R-tree picksplit methods. Now it checks bad ratio and if so then
use simple split: one half of entries to one page, and another part - to
another page.
- protection from buggy picksplit method: GiST will emit an error if picksplit
of first column has that bug. For second and next column it could be a desired
behaviour, because picksplit may take in attention result of picksplit of
previous column.
