问题
I have Amazon EC2 instance running Ubuntu. I have installed and configured PostgreSQL.
Contents of the file /etc/postgresql/9.3/main/pg_hba.conf:
local all all md5
host all all 0.0.0.0/0 md5
Also in postgresql.conf
I have set listen_addresses='*'.
The test command below is successfully starting psql console.
psql -U postgres testdb
Now I am trying to connect pgAdmin4 from MacOS. I have created a SSH tunnel with following command:
ssh -i ~/.ssh/test.pem -fN -L 5433:localhost:5432 ubuntu@mytestdomain.com
Now I have following details in pgAdmin:
When I save, I get this output: Unable to connect to server: server closed the connection unexpectedly. This probably means the server terminated abnormally before or while processing the request.
What am I doing wrong ?
