I thought about a mixture of object orientation and a normal table
for a relational database.
someFunction() is a method for the object/table someTable.
Since AFAIK postgres doesn't support calling methods of types or
objects I thought about a workaround. That's why is ask the above
question.
By the way, does anyone know if there is something like a standard
for object relational databases ? An URL would be nice.
Thanks and Greetings,
