What's the point of creating a schema? - Mailing list pgsql-novice

(Sorry for asking so many questions, but I can't find answers in the
documentation.)

Why would one bother to create a schema (with "create schema blah
blah")?  Isn't a database enough to keep tables, etc. separate?  I can
see that schemas *may* be useful for complicated designs having a few
hundred tables (i.e. one in which name collisions could become a
common problem), but I can't think of any other situation.

Thanks!
