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
where it fits.
