SQL widget problem

[MatejKovacic]

I am using Ubuntu 16.04.1 LTS and installed Orange with the following commands:
sudo apt-get install python3-pip
sudo pip3 install orange3
sudo apt install python3-pyqt5
sudo apt install python3-pyqt5.qtwebkit
sudo apt install python3-pyqt5.qtsvg
sudo pip3 install psycopg2

Then I run orange-canvas and add SQL widget. It draws warning icon and when I open it, it says:
invalid port number: "None"

This can be solved if you enter this to the "server field":
127.0.0.1:5432

My suggestion is if there is no port specified from the user, Orange should use default port (5432), or - there should be another field named port in SQL widget.

And there is another problem: SQL widget says "permission denied to create extension "tsm_system_time".
The problem is, if I connect to psql as postgres user and say CREATE EXTENSION tsm_system_time;, I got an error: extension "tsm_system_time" already exists.

It seems this extension is already installed. Any idea how to solve this?
