What I use is the following:
     location / {
         fastcgi_pass             unix:/tmp/fcgi.socket;
         include                  /etc/nginx/fastcgi_params;
     }
     error_page   502 /maint.html;

My entire site is served from a FastCGI process, so when it's down or  
is restarting, any requests get sent to maint.html.  502 is only  
thrown when nginx can't access the back-end gateway (either FastCGI or  
a proxy), so your maintenance page will only be shown when you're  
actually doing maintenance.
