Sorry for all the questions but do I need to open the putty connection before I run my app ? Thanks again for your time.

Ahah don't worry. I'm more than happy to help wherever I can 
Answering your question, yes you do need to open the putty connection before running your app otherwise it will not be able to connect to the database. You only need to do this once (when you turn on your PC for example) and then leave it open.

Hi there, I'm unsure about what I need to port forward in my router and Putty, I see in your screenshot you have 127.0.0.1:5432 ; does that mean I need to port forward 5432 in my router to my database server ? and also put my public ip address in the host text box in Putty ? sorry for all the questions but I've not worked with tunneling before 
Edit
I think I've done it though maybe not the way you suggested - this is what I've done
Forwarded port 22 in my router to my local Linux box
Forwarded a port xxx in my Putty connection to my local Linux box
Changed the port number in my connection string to xxx
It worked !!! I'm amazed - thanks for all your help

Hi, sorry for taking so long to reply (looong weekend..).
If I understand correctly then yes, that setup should work both locally on your network as well as remotely 
I should probably make a guide on how to set this up because with all the forwarding going on it gets really confusing really fast.
Anyway let me know if you have any more trouble And if you want to make everything a little bit more secure, checkout how to connect using a key pair instead of a username/password

Hi and thanks again, I already use keys - I’ve been using SSH for years it just never occurred to me to use port forwarding in Putty - I run SSH and PostgreSQL on non standard ports which is an added complication- what I used to do was forward the Postgres port in my router which is not ideal - with your method I have the added benefit of SSH security - and as you say it works remotely

Ah! Sorry for some reason I thought you didn't know about ssh keys 
Anyway I'm glad it works It's amazing what PuTTY and SSH can do for such "simple" programs.
On a side note, be carefull about not running ssh on a standard port. You are giving up some linux protections when doing that.

Oh really what exactly ?

This is only true if you use a port above 1024.
Ports bellow 1024 are given some extra "protections" by Linux, one of them being that your program must be executed as root to be able to bind to them. This means that if you use a port >1024 and get infected by something, that something can bind to that port, act like a ssh server and capture everything you are doing.
As usual there are tons of discussions and opinions about this if you want to take a look:
- Why not move SSH to another port? - BSD How To[^]
- Why putting SSH on another port than 22 is bad idea[^]
- Why putting SSH on another port than 22 is bad idea | Hacker News[^]
This is probably overkill for what you and I do but I like to keep it safe (and I had to worry about this kind of stuff on a previous job although I'm not a security expert, not even close, so keep that in mind).
One way to keep both benefits is to keep ssh on port 22 on your linux box but port-forward a random >1024 port on your router to port 22.
Is this worth it? I'm not sure but at least it's one less thing to worry about.

If it's only for you, consider SSH. You can use putty on a Windows machine to do port redirection if you need to. On linux its not much harder. Depends a little on how permanent it needs to be.

Um, you do know that cats only make noises to humans because they're predators, don't you? They interact with each other in complete silence
Have you never seen your cat stretching itself up a wall and making funny, squeaky, screechy noises at a moth, fluttering away above it?
Those funny noises are the human-hearable residue of the cat imitating the sounds that the moth is making (which the cat can hear, but we can't).
So cats only "talk" and make cute noises at you because you're their victim.
I speak as someone who hasn't lived without a cat for the better part of forty years, despite the sh1t-f***-buggery mess cat fur makes of your vocal chords (so don't ask me to sing unless I've been away from home for at least three days, because I won't be able to hit a note).

This something that's really cool to analyse. It's too complicated and messy (and phenomenally/inspiringly educational) to go into it in the CP Lounge, but if you're interested in how animals' (including humans') brains work, it's a fascinating field of research.
I know this because I researched it thirty years ago

And cats only meow because of "humans"? So before humans, cats were completely silent?
Lions do not roar either, except for humans?
It's a nice myth, which does explain something interesting about the arrogance of our species and brain.
