postgres9.0beta2 - vacuumdb - discrepancy between docs & cli

[TEST REPORT]
[Release]:  9.0beta2
[Test Type]:  feature
[Test]:  vacuumdb
[Platform]:  ubuntu
[Parameters]:  -Z
[Failure]:  Yes
[Results]:
postgres@princess:~$ /usr/local/pgsql/bin/vacuumdb -Z -d testy
/usr/local/pgsql/bin/vacuumdb: invalid option -- 'Z'
Try "vacuumdb --help" for more information.

[Comments]:
link to reference doc:
http://developer.postgresql.org/pgdocs/postgres/app-vacuumdb.html

vacuumdb --help also shows the -Z option as the short version of --analyze-only.

The full option works:
postgres@princess:~$ /usr/local/pgsql/bin/vacuumdb --analyze-only -d testy
