Re: Issue with Configuring BDR 1.0.2 in Postgresql 9.4

This is what I have:

# TYPE DATABASE USER ADDRESS METHOD

# "local" is for Unix domain socket connections only
local all all trust
# IPv4 local connections:
host all all 127.0.0.1/32 trust
# IPv6 local connections:

# Allow replication connections from localhost, by a user with the
# replication privilege.
#local replication postgres trust

Morning Brad,

Could you pass along your pg_hba.conf for 10.108.55.92? Your issue may be there.

So, I’m trying to set up a simple two-node Postgres Replication cluster, and things are going ok until I try and set up the DSN. The command I am using is

bdrdemo=# SELECT bdr.bdr_group_create(local_node_name := 'node1', node_external_dsn := 'host=10.108.55.92 port=5432 dbname=bdrdemo');

but when I run that, I receive the following error:

This probably means the server terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Succeeded.

I’m running this on a RHEL 7.3 OS with SELinux set to Permissive.

I also enabled the bdr extension via the shared_preload_libraries lin in the postgresql.conf file, and created the extension btree_gist in the bdrdemo database prior to running the SELECT statement above.

Not sure what I am missing, but any pointers/advice you could give would be greatly appreciated.

Thanks.
