The OID is just a relatively unique database wide row marker -- which
you cannot count on existing in user tables. Nothing more or less. In
some of the system tables it is used as a foreign key to records in
other system tables, but Oid by itself has no such meaning.

Take a look at the 'System Catalog' documentation, and in psql the -E
option will show you the 'system' queries used to retrieve the
information for display in psql.
