Moving on with verification of the same index in the event of B-Tree
index corruption is a categorical mistake. verify_nbtree.c was simply
not designed to work that way.
You were determined to avoid allowing any behavior that can result in
a backend crash in the event of corruption, but this design will
defeat various measures I took to avoid crashing with corrupt data
(e.g. in commit a9ce839a313).
What's the point in not just giving up on the index (though not
necessarily the table or other indexes) at the first sign of trouble,
anyway? It makes sense for the heap structure, but not for indexes.
