PostgreSQL has one and only one storage engine. Unless you intend
working on the source-code of PostgreSQL itself there's no point in
enquiring about its details.
A database is already split over several files, and individual objects
(tables/indexes) may be split into multiple files of 1GB each. You can
spread the load over multiple drives via various RAID setups, symlinks
or, in 8.0 tablespaces.

PS - treat most articles you read on the web with some caution. Most are
poorly researched by people without the experience to write their topic.
I haven't read the article linked above.
