Two quick addendums:

- pg_dump doesn't dump large objects. You should use the following if 
you use large objects.

pg_dump -h /host1/ –p 1234 -Fc /dbname/ | pg_restore -h /host1 –p 56789/ 
/dbname///

- There might be some other issues with the upgrade. I've run into 
permissions issues, data types that were checked more strictly, and a 
couple broken primary keys in my days as an admin. I'm not saying you'll 
run into these, but if you can, do a dry run of a dump/restore so you 
can solve the problems up front.
