There's this page:

http://www.postgresql.org/docs/8.1/static/install-upgrading.html

And take a look at this one too:

http://www.postgresql.org/docs/8.1/static/release-8-1.html

which covers a few issues like encoding problems you might see.  In
versions before 8.0 charset checking was lax, and you might have
characters in your database that are illegal for UTF-8 encoding.  Simple
fix is to let iconv fix that.  Linux has it, not sure about other OSes,
but someone could always download a knoppix disc and boot from it just
long enough to convert the dumps if you don't run linux in your shop.
