    Is the server running locally and accepting

Verify that Postgres is running using:

ps -ef | grep postgres

root@959dca34cc6d:/var/lib/edb# ps -ef|grep postgres
enterpr+    476  1  0 06:38 ?        00:00:00 /usr/lib/edb-as/11/bin/edb-postgres -D /var/lib/edb-as/11/main2 -c config_file=/etc/edb-as/11/main2/postgresql.conf

Check for data directory and postgresql.conf.

In my case data directory in -D was different than that in postgresql.conf

So I changed the data directory in postgresql.conf and it worked.
