Alexander, do you still have the test environments and data lying around that you used for GiST buffering testing last summer? Could you rerun some of those tests with this patch?
I think I can restore test environment and data. Will rerun tests soon.
I rerun some of tests. There are index build times in seconds for old way of parent refind and new way of it.
old new
usnoa2 2385 2452
usnoa2_shuffled 8131 8055
uniform 8327 8359
I thinks difference can be described by round error.
Indexes seem to be exactly same. It's predictable because changing algorithm of parent refind shouldn't change the result.
