Hi This page:
http://www.pgadmin.org/docs/dev/maintenance.html contains info so outdated that it'd be better replaced with a link to the relevant PostgreSQL documentation. In particular, re vacuum: " While this tool is very handy for ad-hoc maintenance purposes, you are encouraged to install an automatic job, that performs a VACUUM job regularly to keep your database in a neat state." which suggests that it *predates autovacuum*.
