Software Setup: PSQL Windows instructions

[joaocaldeira]

The instructions used were:

1. Make sure you have at least one of dbeaver or postgresSQL as instructed in the prerequisites.
2. Same as (2) in the Mac instructions, done from the ssh client (eg cygwin) to create the tunnel.
3. Use dbeaver or the psql terminal (accessible from the start menu once you install postgresSQL) to enter the server, port number, username and database name one by one.
