I created both databases one hour ago for just testing this behaviour. I
started with two identical tables, each with 5000 rows in both
databases. In db1 I opened a transaction, updated the table and left the
transaction open.
In db2 I updated, inserted and deleted a lot and then tried to vacuum.

I tried but it hangs.
