[GENERAL] replication only
i read about the replication possibilities with postgresql. If i just need some replication ( without failover stuff ) to 1 standby server, what would be the best option to go with. Slony i presume, although schema chanages are not propagated. thanks jef peeraer -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

Your description of you requirements is very lacking, so much so that any attempt at suggesting a best option would be pointless. Provide some more information on your requirements and people will be able to answer intelligently. -- Bill Moran Collaborative Fusion Inc. http://people.collaborativefusion.com/~wmoran/ [EMAIL PROTECTED] Phone: 412-422-3463x4023 -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

Provide some more information on your requirements and people will be able to answer intelligently. my apology, i tried to be brief. i've got a main database, where all transactions end up. Daily we make a backup (pg_dumpall) and restore the first database in a sort of backup database. This backup database is mainly used to do reporting. To automate this process for the backup database and to minimize the out-of-sync state, i should like to use replication. The second backup database is only used as read-only, except for some third party software that writes to 1 table. jef peeraer -- Bill Moran Collaborative Fusion Inc. http://people.collaborativefusion.com/~wmoran/ [EMAIL PROTECTED] Phone: 412-422-3463x4023 -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

You'd probably be best with Slony, just don't replicate that 1 table that you'll need to write to. -- Bill Moran Collaborative Fusion Inc. http://people.collaborativefusion.com/~wmoran/ [EMAIL PROTECTED] Phone: 412-422-3463x4023 -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

Skytools (http://pgfoundry.org/projects/skytools/) has a considerably lower learning curve compared to Slony. Nothing wrong with Slony, but recovering from replication problems with skytools is far easier, and it's just much simpler to use -- not as flexible and as powerful as Slony, but if all you need to do is replicate some tables with minimum fuss and without having to learn a new language, then Skytools (based on my personal experience with a cluster and Slony versus Skytools) is my recommendation.

This is probably good advice. For simple cases, Slony's sort of a pain in the neck.
