We fixed GiST. B-tree still has the issue that if you have a checkpoint 
in the middle of an insert, and crash, you might be left with a leaf 
node without a downlink in the parent.

That's relatively harmless, index searches and insertions work without 
the downlink. However, there's code in page deletion that ERRORs if the 
parent can't be found. That should be fixed.
