Finding database names for overnight vacuum

G'day all.

I have a cron job which vacuums etc all of my databases but it does not
work with 7.1.2 because of the change in structure of .../data/base.

It currently says:

for q in /usr/local/pgsql/data/base/*; do
blaa
blaa
done

How does one get an equivalent list of all databases from 7.1.2?
(and where is it documented?)

Cheers and thanks,
Stephen Davies
