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:
FATAL: could not connect to the server in non-replication mode: fe_sendauth: no password supplied
DETAIL: dsn was: connect_timeout=30 keepalives=1 keepalives_idle=20 keepalives_interval=20 keepalives_count=5 host=10.108.55.92 port=5432 dbname=bdrdemo fallback_application_name='bdr (6427018047201618294,1,16384,):bdrnodeinfo'

server closed the connection unexpectedly
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.
