Thus, the details in this case are: - ssh -i vm_paiyroll.pem awsuser@18.168.196.169 - foo=> \conninfo You are connected to database "foo" as user "dbcorexyz" on host " live-paiyroll-db-c702180bbf.ci22uuz4wz33.eu-west-2.rds.amazonaws.com" (address "172.31.4.93") at port "5432". SSL connection (protocol: TLSv1.3, cipher: TLS_AES_256_GCM_SHA384, compression: off) When I connect via pscopg, I first set up an SSH tunnel through the EC2 host, and then connect. Thus the details in this case are: - bastion_host.ssh_host is '18.168.196.169', bastion_host.ssh_usernme is awsuser - <psycopg_binary.pq.PGconn [INTRANS] (host=localhost user=dbcorexyz database=foo) at 0x7f6bfd554a90> I *am* dealing with multiple db connections (am working on some replication tooling) but AFAICS, both connections are to the same place.
