even if you only type "vacuum verbose" it takes _very_ long.
I deleted _all_ records with "delete from mytable;" before.
A drop and a new create is faster. But what is when you delete (maybe
100000) rows but keep 100 in the table?
I use 6.4.2 on NetBSD/i486 (that box makes gets 12MBytes/sec via the
filesystem out of the drives)
