Answer 1

quick howto on debian to remotely access postgres database on server from the psql client: (the changed config is doc'd in the files):

1. edit /etc/postgresql/10/main/postgresql.conf with listen_address *
2. edit /etc/postgresql/10/main/pg_hba.conf and add line in the end with host all all 0/0 md5
3. create login role postgres=# CREATE ROLE remoteuser LOGIN WITH PASSWORD 'foo'

4. sudo /etc/init.d/postgresql restart changes take effect

5. login from clientside with psql --host=ipofserver --port=5432 --username=remoteuser --password --dbname=mydb

6. the password is interactivly asked which in this case is foo
