OK, I guess I could treat one as 'schema master' and pg_dump schema + data across to the other once a night, once all activity has stopped and standard replication completed. > >> Any experiences/thoughts? > > My experience is with Bucardo, which should do the job admirably > (but with the data only).

My experience is with Bucardo, which should do the job admirably (but with the data only). My advice would be to just set up a test system and try rubyrep and Bucardo out.

[GENERAL] Multi master use case?
Hello, A client of ours has always had problems with slow internet connectivity - they are in a part of the country where that is a problem. There are a few hundred staff sharing a couple of asymmetric (ADSL) connections. One issue is with accessing their web-based Postgres app, which we host. Now they don't want to run it internally for a lot of the usual reasons, not least they have many distributed workers and trying to serve data from an already congested spot would be a non starter. Is this a case for multi master do you think? I.e. running one on the internet, one locally. Looking through the wiki http://wiki.postgresql.org/wiki/Replication,_Clustering,_and_Connection_Pooling it seems there are a few solutions that have now gained maturity. Something like rubyrep sounds ideal. It would have to deal with a) a flaky local connection b) changing schemas (new tables, fields, views etc.) as well as data Create/update/delete frequencies are reasonably low, generally individuals updating single records so of the order of thousands per day max. Any experiences/thoughts?
