Fine-tuning the new db function interface
#
# Check, wether we have to regenerate the database function interface.
#
# - During initial setup, there are no db-functions, so nothing has to
# be done.
#
# - During regular startup of the server, the generation of the stub
# interface happens in the *init procs (hopefully this is always
# sufficient, but seems so)
#
# - During reloads of acs-db-*-procs, the base classes are interface
# objects are recreated and cleaned up from all prior definitons,
# which means that in this situations, we have to regeneate the
# interface.
#
# - One might call manually the regeneration, when database functions
# have been altered and no restart is desired.
