There is no such thing as a "default value". There is a "default _expression_" though. It should be available in the system catalogs as part of the definition of a table. But I'm of the general impression that attributing some special significance to a value in the database because it happens to have been computed by a default _expression_ instead of some explicitly supplied value is generally a wrong approach to take. The data should be interpreted in an internally self-sufficient way.

Can you distinguish the case of the actual value matching the (computed) default?
