Teodor Sigaev 4eaf7eaccb Add missing and dangling downlink checks to amcheck ... When bt_index_parent_check() is called with the heapallindexed option, allocate a second Bloom filter to fingerprint block numbers that appear in the downlinks of internal pages. Use Bloom filter probes when walking the B-Tree to detect missing downlinks. This can detect subtle problems with page deletion/VACUUM, such as corruption caused by the bug just fixed in commit 6db4b499. The downlink Bloom filter is bound in size by work_mem. Its optimal size is typically far smaller than that of the regular heapallindexed Bloom filter, especially when the index has high fan-out.
