Attached draft patch uses RelationGetNumberOfBlocks() to size each of the two Bloom filters that may be used by amcheck to perform verification. The basic heapallindexed Bloom filter is now sized based on the conservative assumption that there must be *at least* "RelationGetNumberOfBlocks() * 50" elements to fingerprint (reltuples will continue to be used to size the basic heapallindexed Bloom filter in most cases, though). The patch also uses the same RelationGetNumberOfBlocks() value to size the downlink Bloom filter. This second change will fix your problem very non-invasively. I intend to backpatch this to v11 in the next few days. -- Peter Geoghegan
