I always show all pins in my schematics, even if they are not used on the component. I name them "NC", set the electrical type as passive, and give them distinct pin numbers. When placing these components on a schematic, I put a "no-erc" marker on the end of each unused pin.
I do this so that when I read the schematic later, I see that I have thought about what to do with those pins, rather than scratching my head and wondering "Did I overlook these unconnected pins?". I think it's good practice to explicitly show unused pins and to show that they are in fact unused and unconnected. Naming the not-connected pins "NC" makes it easy to search through the netlist to find them, and make sure they aren't connected to anything.
