Thanks for your patch.
I tested your patch and tried some cases, like large indexes, different types of indexes, it worked well.
Besides, I noticed a typo as follows:
+ /* Estimate size for index vacuum stats -- PARALLEL_VACUUM_KEY_STATS */
"PARALLEL_VACUUM_KEY_STATS" should be "PARALLEL_VACUUM_KEY_INDEX_STATS".
