Postgresql replication

Hello,

 

Currently we have only one database accessed by the headquarter and two branches but the performance in the  branches is very poor  and I was invited to discover a way to increase it.

 

One possible solution is replicate the headquarter DB into the two branches.

 

I read about slony-i, but then the replicated DBs will be read-only.

 

Pgcluster is a sync solution and I think is not fited for us becase the replicated DBs will be located remotely and we have a lot of updates on the DBs.

 

I think I´m looking for a master-slave assynchronous solution. I know pgReplicator can do it, but I think the project is not active any more.

 

Are there another solutions?

 

Thanks in advance!
