How are loose pins on a backhoe repaired? Do they machine and sleeve the worn holes or install oversize pins? Are oversized pins a standard repair item? I don't plan on doing this myself but I'd like to know how it's done.

Typically you replace the bushing and the pin. If the seat for the bushing has been egged out it needs to be rebuilt by welding and then line bored...
Most folks don't understand how cheap grease is until they pay this repair a few times. ....

Like Harvey says as long as they're not egged out it's a fairly simple and easy thing to do. I've done mine on my backhoe and skidsteers. A little heat from a acetylene torch is required usually though I have done it without it. The alternative is using a die grinder to section it then pound out the sections. Installing takes some heat around the bushing area (not the bushing), lube and patience. Chilling or freezing the bushing helps too.
I make my own pins from hydraulic piston rod. Got that "secret" from a local hyraulic repair shop. And it's about $5-15 a foot. Cheap when you compare dealers want. Cutting is easy with a cutoff wheel or even a sawzall.
The other thing I've done when possible is use an adjustable "poor man's" in line boring bar or straight reamer available from a good tool-and-die supplier for about $50. Then I up-size the pin size. ....
