Arrays in PostgreSQL

Hi,

since I have serious problems with some of the features of the JDBC
driver I am searching for a different way to store the following
structure efficiently in the PostgreSQL database.

How can I store an array of double numbers and retrieve it without
creating a row for each entry? I read something about arrays in
PostgreSQL and I wonder if this feature can be used to retrieve the
whole array at once instead of retrieving the entries sequentially?
