Hi. I've had experience with both BDR & pglogical. For each replication slot,
postgres saves a LSN which points to the last xlog entry read by the client.
When a client does not reads xlog, for example, if it cannot connect to the
server, then the distance between such

Just a guess: How did you blocked the port? Depending on that, you could be
blocking only new connections, but connections already established would
continue to transmit data; remember BDR only reconnects when connection is lost.

Hi. I currently have a two-server BDR replication setup. Apart from the two
master nodes, I have another two servers which I want to have read only
replication for some tables only.
I first had to deal with some trouble regarding CREATE EXTENSION being
replicated by BDR, and that causing the
Hi.
It's not like BDR is unable to replicate triggers across the cluster: BDR is
not intended to do so.
BDR replicates everything that happens inside a transaction; that includes both
SQL run directly from the application, as well as changes made by triggers and
extensions. As the changes are

Cleanup some space on that device. Maybe your "pg_log" folder has some space to
free. If that doesn't helps, you may need to forcefully add more space. There's
not really much alternatives there.

Hi.
I had to implement something similar some time ago. Basically, a group of
database servers (postgres) geographically distributed, with each one having a
group of servers in each datacenter, and each server preferring the nearest
database server, but allowing connections to a further one if

then there's no current solution for that.
But I would go a little bit further: is it a real problem? I mean, even being a

Hello. BDR works on a per-database basis, so there's nothing like what you are
looking for. However, if you initialize a BDR custer with bdr_init_copy, you
will get all existing databases added to replication. Then, as part of the
creation of new databases, you can use bdr_group_join function,
Block based replication is the replication mechanism postgres incorporates
natively. It's, in brief, sending all the file-level changes to all the slaves,
so the data folder is always the same. It's like having a replicated folder,
not including logs and some other things.

you tried doing the same, on both server, on an empty database created from

What's the purpose of such configuration? Doesn't makes sense for me. The only
reasonable case where you would want to put the data folder on a shared storage
is for usage with warm standby, where you can have a secondary server which
serves as a read-only replica, and can be rpomoted to master

Some time ago I had to setup a replicated file system between multiple linux
servers. I tried everything I could based on postgres, including large objects,
but everything was significantly slower than a regular filesystem.
My conclussion: postgres is not suitable for storing large files
Hi. I think pgpool-II can do that job for you. It's a middleware, so you can
use it without even changing your app code(but your postgres configuration). It
suppoerts many clustering functions, including replication, failover, and a lot
more; it also supports partitioning. so that may be
Hi. I currently have two servers in different geographical locations; both of
