I solved this error by putting container_name in the host i,e. 

db:
  db:
  type: postgres
  datasource: host=db-postgres port=5432 user=postgres password=caDbPass12345 dbname=fabriccaserver sslmode=disable  
  tls:
      enabled: false
      certfiles:
      client:
        certfile:
        keyfile:

Previously, i was entering localhost and also tried with 127.0.0.1 and after that i saw that in my docker-compose.yaml my postgres service was under different network and ica.org1.example.com was under different network which i fixed and also had to do docker network prune after killing and removing all the docker processes.
