I should have explained more in my previous post.  In your command line
you have:

ssh -L5555:localhost:5432

I am assuming you then use 5555 as the port number in your connection
string from psql or pgAdmin and the connection succeeds.

When you set up the tunnel from pgAdmin I am not seeing a setting for
the listening port.  So the solution is to either find some way to
specify the port from the pgAdmin dialog or find the port that pgAdmin
is setting on its own. My previous suggestion was an attempt at forcing
the port to one you have been using. Not sure if that will work. In the
event it does not you could see if you can find what port is actually
being used and adjust your connection strings accordingly.
