There's this page:
http://www.postgresql.org/docs/8.1/...-upgrading.html
And take a look at this one too:
http://www.postgresql.org/docs/8.1/...elease-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.

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match
