Log Message:
Reduce WAL activity for page splits:

Currently, an index split writes all the data on the split page to
WAL. That's a lot of WAL traffic. The tuples that are copied to the
right page need to be WAL logged, but the tuples that stay on the
original page don't.

this patch killed both of my OpenBSD buildfarm members

Please note that zebra died for a different reason the second time (not
enough shared memory).

yeah that's because initdb is leaving the shm-segments there on a failure.
This resulted in the out-of-shm failure on the following run which I have manually cleared now ...
