The optimization for inserts into BRIN indexes added by c1ec02be1d79 relies on a cache that needs to be explicitly released after calling index_insert(). The commit however failed to invoke the cleanup in validate_index(), which calls index_insert() indirectly through table_index_validate_scan(). After inspecting index_insert() callers, it seems unique_key_recheck() is missing the call too. Fixed by adding the two missing index_insert_cleanup() calls. The commit does two additional improvements. The aminsertcleanup() signature is modified to have the index as the first argument, to make it more like the other AM callbacks. And the aminsertcleanup() callback is invoked even if the ii_AmCache is NULL, so that it can decide if the cleanup is necessary.
