Excellent David, them I will do that first, them add pushdelta to my sync and continue testing. Thanks.

Hi Periko, If you can start it with a copy of the master db you save yourself a step. Otherwise you will need to initialize the target in Bucardo either using a onetimesync=1 in the sync definition or copy over using pg_dump out-of-band. Bucardo will not load the data in the target explicitly without being told to, so if you just started with empty data it would only copy the rows over as changes were made to them, probably not the effect you were looking for.

Bucardo user inside postgresql DB must be superuser? Or this step can be done with postgres main user? thanks.

Putting a language into a database requires two steps: having it compiled into Postgres (the apt-get call in this case) and then loading it into individual databases via CREATE LANGAGE.

Issues with ubuntu 14.x For some reason the commando bucardo install tell me that the language plperlu is not installed, but ubuntu say is already install. INSTALLATION FAILED!

Yup, if you need a writeable database cluster you need to use a logical replication system like Bucardo. The main difference between the master-master examples and normal master-slave would be that when defining the sync instead of having `bucardo add sync foo dbs=source:dbA,source:dbB,source:dbC` you just need to provide the list of the individual databases. Bucardo assumes (unless otherwise told) that the databases are given in the order of source, target, target, […]. So you’d be looking at `bucardo add sync foo dbs=dbA,dbB,dbC` to setup a sync from dbA to dbB and dbC.

Re: [Bucardo-general] Master-Slave Setup?
Yes, I already did psql replica master-slave, works but our pentaho implementation with in OPENERP don't allow us to run openerp+pentaho in the slave. This setup require read/write to the database and the slave is read-only which our reports fail. This is why we need something that allow us to have a copy of our psql read/write mode and some one told us about bucardo. This can help to fix our issue right? Thanks for your help and time.

Re: [Bucardo-general] Master-Slave Setup?
Hi Periko, While Bucardo does support Master/Slave replication, PostgreSQL’s native replication supports this quite nicely out-of-the-box. Not to discourage you from Bucardo for this purpose, but you’ve verified this wouldn’t be sufficient for your needs? If you’re looking for a Bucardo example, you can start with https://bucardo.org/wiki/Bucardo/pgbench_example . It’s not completely up-to-date; it’s written for the older Bucardo 4, but substituting “bucardo_ctl” with “bucardo” might get you most of the way there.
