I get this below error while trying to set up BDR when both the nodes are on different hosts.
SELECT bdr.bdr_group_join(local_node_name := 'node2',node_external_dsn := 'port=5599 dbname=bdrdemo host=<ip of node2> user=postgres', join_using_dsn := 'port=5432 dbname=bdrdemo host=<ip of node1> user=postgres');
ERROR: establish BDR: FATAL: no pg_hba.conf entry for replication connection from host "[local]", user "postgres"
Both the hosts have a pg_hba.conf like:
# "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:
host all all ::1/128 trust
# Allow replication connections from localhost, by a user with the
# replication privilege.
local replication postgres trust
host replication postgres 127.0.0.1/32 trust
host replication postgres ::1/128 trust
host all all 0.0.0.0/0 trust
host all all ::/0 trust
host replication postgres 0.0.0.0/0 trust
host replication postgres ::/0 trust
Changes to postgresql.conf
listen_adresses = '*'

What has gone wrong here?
