postgresql and java2

Hi:

Does anybody knows if the JDBC driver maps the new SQL 3 types (ARRAY and
STRUCT) with the proprietary array and user-defined types of PostgreSQL? To
put it another way: when I access an array (for instance) in PostgreSQL
through the JDBC driver, does the driver returns a SQL 3 ARRAY
(java.sql.Array) or a Java Object (java.lang.Object)?
I’m sorry if this sounds “newbie”, but this is the first time I use an
ORDMS…

Thanks in advance
J.
