**Setup Nginx**

First, lets add a symbolic link to the directory where you intend to place all your web files in.

```
sudo ln -s /usr/share/phppgadmin /var/www
```

Next, lets create a server block for phpPgAdmin. Create a file /etc/nginx/sites-available/phppgadmin with the following contents.

```
# Server block for phppgadmin service
server{
        server_name     phppgadmin.example.com;
        root            /var/www/phppgadmin;

        access_log      /var/log/phppgadmin/access.log;
        error_log       /var/log/phppgadmin/error.log;

        location ~ \.php$ {
                try_files $uri =404;
                fastcgi_split_path_info ^(.+\.php)(/.+)$;
                fastcgi_pass unix:/var/run/php5-fpm.sock;
                fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME /path/to/your/www/postgres$fastcgi_script_name;
                include /etc/nginx/fastcgi_params;
        }
}
```
