Question: Are there plans to provide a feature in PostgreSQL that one
can have foreign keys for purely documentation purpose - I know, one
could use a modelling tool and just not implement the FKs, but my
reality is, there is hardly ever a modelling tool involved.
The answer to the specific question is, no, I don't believe that there
any plans to implement purely documentary foreign keys.
Recent versions of the SQL spec have a NOT ENFORCED option for
constraints, which is what I think you're looking for here.
If somebody came with a well-thought-out patch to add that feature,
we'd likely take it. But this is definitely a "scratch your own
itch" situation; I don't know of anyone already working on such
a thing.
NOT ENFORCED would be a great boon to administrators writing regular
archive/purge operations.
