What is new in 8.0 is the ability to tell vacuum to sleep a period of

Depending on what you're doing you could also use contrib/ltree i
'index covering', so even when it accesses
a table via an index it still has to read the base table. This is why if
you need to read the entire table it's faster to seqscan than index
scan.
