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contains info so outdated that it'd be better replaced with a link to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*.
