Re: "Failed to connect to Postgres database" - Mailing list pgsql-general

Thanks Daniel.

After adding the password, now ssh connection to the cluster fabmnet works:

postgres=# \l
                              List of databases
    Name    |  Owner   | Encoding | Collate |  Ctype  |   Access privileges

(4 rows)

postgres=# \password
Enter new password:
Enter it again:
postgres=# \q

postgres=#

And may be the fact the it's compulsory to add a password is testified also by the fact that changing the ownership of the database while adding a password, lets connect with ssh to the database:

postgres=# CREATE USER fabmnet_admin;
CREATE ROLE
postgres=# ALTER USER fabmnet_admin WITH PASSWORD 'A';
ALTER ROLE

postgres=# ALTER DATABASE fabmnet_ca OWNER TO fabmnet_admin;
ALTER DATABASE
postgres=# \l

Now I have to fix the interface between fabric-ca and postgresql-11 on both sides. And I will let you know how it is going
