If there is no fix for vacuum, I suggest to change the filesize before
splitting
back to just below 2 Gb (2Gb - 8k). Else vacuum will only work for tables
up to 1 Gb, and it did work up to 2 Gb before.

I am the one who suggested 1 Gb, so I had my eye on this issue.
I still think 1 Gb is good for various reasons, but only if vacuum works.
