Howdy!   I bet you're a bit taken aback by the discussion that ensued, and 
even more confused than before.

You are actually asking about two related features:

Tablespaces, which allows designating different directories/volumes for 
specific tables and indexes at creation time, and:

Partitioned Tables, which allows the division of large tables and/or indexes 
horizontally along pre-defined criteria.

The first, tablespaces, are under development and may make it for 7.5, or 
maybe not, but certainly in the version after that.

The second, partitioned tables, is NOT under development because this feature 
lacks both a programmer and a clear specification.
