The part after "but" reads oddly to me. I would just delete the sentence.

The other CONCURRENTLY fix ("Avoid race condition" in the release notes) is
broader, so please replace the above entry with something like this, not even
mentioning prepared transactions:

* Fix causes of `CREATE INDEX CONCURRENTLY` and `REINDEX CONCURRENTLY` writing
corrupt indexes. You should reindex any concurrently-built indexes.

> * Disallow `ALTER INDEX index ALTER COLUMN col SET (options)`.

I'd drop this since the feature was unusable before.

Please add something like:

* Fix REINDEX CONCURRENTLY to preserve operator class parameters that were
attached to the target index
