Certain pickles are brined and pickled using vinegar and often preservatives. Such as the one's that you find on the shelves of supermarkets. But others that are found in the refrigerated deli case may have only water, spices, garlic and not much else (the brand I purchase, Batampte, are made this way). Because there is no preserving agent, such as vinegar, these can go bad and grow bacteria of not refrigerated.
Yes, they really should be to prolong the storage time. It does effect the fresh flavor slightly. Think of it this way, if they are refrigerated at the store they should be at home. At the store you will see produce like onions, potatoes, tomatoes, and many fruits all stored at room temperature. On the other hand, lettuce, cucumbers, green peppers, carrots, celery, etc are always stored in refrigerated displays.
Canteloupes need refrigeration when ripe. This prevents them from over-ripening. I always wash the outside with soap and water before cutting.
