Hi Mircea, Hayato,

I tested the v4 patch on 19devel with a few different thread/partition
combinations.

The updated API looks much better now. I verified that:

   - parallel loading works correctly with -j
   - uneven partition distribution (for example 5 partitions with 2
   threads) also works fine
   - serial mode with -j 1 works again as expected

The workers appear to run concurrently, and VACUUM time remains relatively
small in my tests.

Overall, the new approach looks much cleaner and more flexible compared to
the earlier versions.

Thanks again for the update.

Best regards,
Lakshmi
