Re: replication?

Hi,

from: http://www.postgresql.org/idocs/index.php?backup.html :
"pg_dump -h host1 dbname | psql -h host2 dbname"

You could run this out of cron on your internal DB server (host1)

And use a firewall rule like:

# Allow internal DB server to use TCP for DB dumps
pass in quick proto tcp from ip_of_host1 to ip_of_host2 port = 5432 flags
S/FSRPAU keep state

The rule above is for IP Filter http://coombs.anu.edu.au/~avalon/

Does postgres support replication? I think this is the feature I need.
I have a table in one db that I need to use from another db on another
machine. The first db is behind two firewalls (for a good reason =) and
the second needs to be hung out on the internet, so I can't really use
the same db. But I would like to have the table on the internet Pg
install to be updated whenever the master table behind the firewalls is
updated. It doesn't need to be real-time, but maybe once every hour or
half hour. I certainly have no problem cheating and just copying a file
over or something if that will work. I looked through the docs but
didn't see anything about replication in the Administrator manual, where
I assume it'd be discussed. I did see a vague reference to a
replication toolkit in the release notes, is this what I'm looking for?

Thanks,
Fran
