open db version 8.1 with postgresql version 8.2

Hi all

Could not find any reference to this kind of problem in the archives... (or
maybe I was not good at searching it... My apologies if so). Trying to update
from ubuntu 6.10 to 7.04, something went wrong and botched up my posgresql
8.1 server (would not start), among many other things.
So I spent a month trying to figure it out, finally gave up. I did a fresh
install of Feisty Fawn, which includes postgresql 8.2. Now before that I was
able to back up the whole main directory for 8.1, but I was not able to do a
pg_dumpall. Now I have a working 8.2 installation and all my data backed up
in a 8.1 main directory.
How can I load this into 8.2?

Thanks in advance for your kind help...
