Migration page is out of date

http://www.postgresql.org/docs/9.0/static/migration.html

This page:

a) has insufficient coverage of pg_upgrade
b) ignores parallel pg_restore
c) piping pg_dump is by no means always the fastest method

I'll write up a new version later, just wanted to put this note on the
ML so that somebody would bug me before the end of 9.1 beta.
