pg_dumpall (7.3) 'public' schema bug

Hi,

Went to upgrade from postgresql (RedHat's postgresql
rh-postgresql-7.3.6-7) to Fedora core 3 postgresql
7.4.6-1 and encountered a problem. If nothing else this
is worth a note on the 7.4 upgrade doc page.

I deleted the 'public' schema from my databases
in 7.3, now in 7.4 they are back. I suppose it is remotely
possible that I really didn't delete 'public' in 7.3,
I can't recall the last time I looked, but I'm sure
I must have checked at the time I deleted public.

Ran pg_dumpall on 7.3. After feeding the ouput to psql
on 7.4 I got:

$ psql babase
