Class Db-Class [Tinaa]

Class Db-Class

Metaclass for PostgreSQL aware classes. It takes
two additional arguments in DEFTABLE: :INDICES (which slots are used
as indices) and :CONNECTION-SPEC, which specifies how the class should
connect to the database (its format is the same as in
POSTMODERN:CONNECT-TOPLEVEL). If :CONNECTION-SPEC is not provided,
SUBMARINE assumes it is a class created just for the sake of
inheritance and does not create any tables for it.
