I think arrays are one of the cool features of postgres
(along with gist indexes).
Here are some common uses:
- Tree representation (the genealogical from child to ancestors approach)
- Storing of polynomial formulae of arbitary degree
checkout the intarray package in contrib for further info.
I think pgsql arrays provide a natural solution to certain problems
