Hello, I am inclined to add full support of mapping primitive arrays onto native DB arrays (Postgres first, then maybe for Oracle).
We would like to run SQL aggregations on a lot of double[] arrays and mapping onto @Lob or @ElementCollection does not really work here. It is a general question how to support new DB types. I know I will have to implement either ValueHandler or a Strategy but I am unable to locate any example how actually do this for normally non-supported native DB type... Since primitive arrays are mapped to blobs, I'd think BlobValueHandler could be an example, could you confirm this? SQL_ARRAY appears in a few places in the code (i.e. DBDictionary), so it seems there is some infrastructure to support SQL arrays but how to use it? Should org/apache/openjpa/persistence/jdbc/AnnotationPersistenceMappingParser.java be extended too if I'd like to add schema synchronisation? Some generic example in the documentation would be a real helper.
