Refer to the System Catalogs chapter within the Developer's Guide
section
of the documentation. In addition, if you start a psql session with the
-E option,
you will see how all these \d commands are generated.
I would love to hear there is a standard about system catalogs, but I've
never heard
of one and I doubt there will be one ever in the future.
