A note on pg_upgrade and missing "pg_upgrade_support.so"

Hi

Just a quick note for anyone else building 9.0 from source and experimenting
with pg_upgrade - if you get a message like the following when running the
pg_upgrade binary:

pg_upgrade_support.so must be created and installed in
/path/to/pg90/lib/postgresql/pg_upgrade_support.so

you need to build the the separate "pg_upgrade_support" as well.

Also, the current first hit on Google for "pg_upgrade" is this page:

http://www.postgresql.org/files/documentation/books/aw_pgsql/node267.html

which is hopelessly outdated (the "pg_upgrade" utility described appears to
have been obsoleted 5 years or so ago, see:
http://anoncvs.postgresql.org/cvsweb.cgi/pgsql/contrib/pg_upgrade/Attic/pg_upgrade
)

HTH
