Hi all, Before I start working on this code I would like to get any feed back from others who have worked with the Serialize package or have created custom data types in Postgres. Two problems with the current Serialize code are that you need to know the type of class stored before you can read it back and if the record with the oid field is deleted the serialized record the oid points to is not deleted. What I would like to do is create a new user defined data type for Postgres called serialized that would contain two oid', one pointing to the table for the serialized object and one pointing to the record in that table. I have never worked with user defined types in Postgres or with the JDBC. I suppose that in Java the serialized type would be implimented as a array of two integers. It does not seem that there is any way to fire rules or triggers on data types, so the user would still need to add triggers on tables that contain serialized fields to handle deletes and updates. Two generic functions could be created, though, that would handle all classes. Any comments on this idea?
