Here is new version of the patch for GiST VACUUM.
There are two main changes:
1. During rescan for page deletion only know to be recently empty pages are rescanned.
2. I've re-implemented physical scan with array instead of hash table.
Thanks!
Merry Christmas and happy New Year.
Best regards, Andrey Borodin.
