We have PostgresSQL cluster with 1 master and 2 slave configuration , we want to enable logical replication from Slave , as the master a pretty work heavy database , we don’t want to put more load on DB , Is it possible if we can start both type of replication from any slave currently replicating through streaming replication
we have setup with master it worked , not sure with slave , we did few test run in older vesrion which failed
No, the logical replication primary cannot be a streaming replication standby server.
I'am actually working on the logical replication between my master on Windows and slave on Linux.
I want to transfer all my datas to my slave with logical replication Postgresql.
My postgres on Linuw will be working as docker container.
During the replication, when my container restarted, I have the impression that data were streaming are duplicated, for one table on master with 2,5 Gb of size, I find 5,3 Gb on my slave.
Does it possible that data are duplicated ? There is a way to continue the streaming normally even if docker container restart ?
Thanks a lot
I'd like to have my slave Postgres DB, which is is hosted on Heroku, replicate from a master DB on my laptop. Is this possible? With version 9.6 or 9.4
I read the question: Follow external database from Heroku
but it was for version 9.1
If you speak of streaming replication, then it is not possible and will never be I think. Heroku shares DATABASE - not cluster and streaming replication would require the whole cluster and REPLICATION role access.
Say I have two remote servers 10.0.0.1 and 10.0.0.2. In both the servers I have postgresql database installed with the same databases. Now what I need is, whatever changes or alterations that are done to the database on server 10.0.0.1 should automatically be replicated to the database on server 10.0.0.2.Is there any way to do this automation process? If So, Please suggest me the best and most efficient way of doing this. The version of postgresql I am using is 9.5.3.
That article by Digital Ocean seems to describe every step well enough — how to setup master slave replication on postgresql
I run a Glassfish app server (3.1.2) with a JDBC pool connecting to 1 DB instance.
Now I created a replication setup with a second DB node. I like to loadbalance the DB by allowing read access to the replication slave.
Can I do this by GF configuration or does my application implementation need to take care of this ?
Thanks for any light

PgBouncer PgBouncer Wiki does this job.
You still connect to 1 DB IP (the pgbouncer instance) and it will handle the Postgres Side with 2 or more DB instances.
