If you are looking for a column based dbms, you might want to check out
Monet - it is a columnar database.

For some applications, columnar databases can be much faster than
traditional rdbms systems. However, column based databases are not a
'one size fits all' answer.

you read your tables by column, rather than by row??
SQL queries are inherently row oriented, the fundamental unit of storage
is a 'tuple', which is a representation of a row of a table.
I believe what is referring to is the disk storage organization, clustering
a single column from multiple rows together onto a page. For example, if
your typical use of a table is to read one particular column from a large
number of rows, this could (in theory) improve performance.
AFAIK, PostgreSQL doesn't support this.
