This is an extremely straightforward question. “How do I connect to Postgres DB installed on a digitalocean droplet, from an external client via command-line or via third party apps like PSequel (available for MacOS) or PGAdmin?”. I am surprised that there is no direct tutorial to explain this in plain simple words. Here is what I did so far:
/etc/postgresql/9.5/main/pg_hba.conf
to host all all 0.0.0.0/0 md5
and in /etc/postgresql/9.5/main/postgresql.conf
added listen_addresses='*'
sudo service postgresql restart
psql -h <IPv4 address> -p 5432 -U sammy -d sammy
. However I get the error psql: FATAL: password authentication failed for user "sammy"
How do I connect to postgres server? I would highly recommend digitalocean’s moderators to write a detailed but simple blog on “Connecting to Postgres from external client, along with best practises.”

You missed another step of allowing 5432 port into firewall. Type the following command before connecting to remote postgres connection:
This answer may help to those who are facing trouble to connect remote postgres connection.
Oh, I found a solution to the above accidentally - it is related to the escaping characters:
this worked (at least in my case):
ssh sammy@ipaddress “psql -c "alter user ‘sammydbuser’ with encrypted password ‘some_string’;"” ssh sammy@ipaddress “psql -c "grant all privileges on database ‘sammydb’ to ‘sammydbuser’;"”
note: the quote goes before psql command, then after the switch -c, you have to quote the actual command, but with an escape character. same applies to closing the quotes …
I sincerely hope this might help someone else …
