After further investigation I have found that the reason why the query is
slower on 8.0.3 is that the hash and hash joins are slower on the 8.0.3.

So the question comes down to : Why are hash and hash joins slower? Is this
a postgres configuration setting that I am missing? Is the locale still
screwing me up? I have set the locale to 'C' without any improvements. Is it
because the column type is a varchar that the hash is slower?
