Re: PostgreSQL replication solution?

The scenario is the following:
I have a main database on a server probably this will be the master.

With this replication we want first to make a copy of this database which
will be at another location(another company) with 1 time/day sincronization,
so this will be a slave which will contain a part of the database(so not all
the tables) ~ asyncronus replication

and

we also would like to make a backup server in our local LAN which will
contain a complete backup of the main database in case of the server fail.

We would like a free solution if possible,
I read about Slony, what about erserver? http://www.pgsql.com/download/ or
http://gborg.postgresql.org/project/erserver/projdisplay.php

Did anyone used it? Which is better to use?

Thanks for any tipps.
Andy.
