Alexander Korotkov d114cc5387 Improve checking of child pages in contrib/amcheck. ... This commit eliminates lossiness in check for missing parent downlinks in B-tree. Instead of collecting lossy bitmap, we check for missing downlinks while visiting child pages referenced by downlinks of target level. We traverse from previous child page to the subsequent child page by right links. Intermediate pages are candidates to have lost parent downlinks. Also this commit introduces matching of child high key to the pivot key of it's parent.
