Make btree index structure adjustments and WAL logging changes needed to
support btree compaction, as per proposal of a few days ago. btree indexpages no longer store parent links, instead they have a level indicator(counting up from zero for leaf pages). The FixBTree recovery logic isremoved, and replaced by code that detects missing parent-level insertionsduring WAL replay. Also, generate appropriate WAL entries when updatingbtree metapage and when building a btree index from scratch. I believebtree indexes are now completely WAL-legal for the first time.initdb forced due to index and WAL changes.1 parent4df0f1d commit70508ba
