Cathy is credited as "Construction Pony" in Castle Mane-ia. It's odd, yes, but there aren't any other side characters in the episode aside from the beekeeper. We could always ask Cathy on Twitter if she remembers voicing this character.

As for whether Parcel Post and the beekeeper are the same character... Same design, same mane style, same eye color. Seems like little room for error, considering the beekeeper's cutie mark isn't shown.
