The case that came to mind was an index broken by a glibc update with breaking changes to the collation sort order
underlyingthe index. If the breaking change has already been live in production for quite some time before a DBA
notices,they might want to quantify how broken the index has been for the last however many days, not just drop and
recreatethe index. I'm happy to drop that from the patch, though.
