Based on the patch in
https://openacs.org/forums/message-view?message_id=1009320 and the discussion in this thread I use now the current version of file which overrides content_type__drop_type.
myfirstpackage-drop.sql:
create or replace function content_type__drop_type(varchar,bool,bool) returns int4 as '
declare
drop_type__content_type alias for $1;
drop_type__drop_children_p alias for $2;
drop_type__drop_table_p alias for $3;
table_exists_p boolean;
v_table_name varchar;
is_subclassed_p boolean;
child_rec record;
attr_row record;
begin
select
count(*) > 0 into is_subclassed_p
from
acs_object_types
where supertype = drop_type__content_type;
if drop_type__drop_children_p and is_subclassed_p then
for child_rec in select
object_type
from
acs_object_types
where
supertype = drop_type__content_type
LOOP
PERFORM content_type__drop_type(child_rec.object_type, ''t'', drop_type__drop_table_p);
end LOOP;
end if;
for attr_row in select
attribute_name
from
acs_attributes
where
object_type = drop_type__content_type
LOOP
PERFORM content_type__drop_attribute(drop_type__content_type,
attr_row.attribute_name,
''f''
);
end LOOP;
select
table_exists(lower(table_name)) into table_exists_p
from
acs_object_types
where
object_type = drop_type__content_type;
if table_exists_p and drop_type__drop_table_p then
select
table_name into v_table_name
from
acs_object_types
where
object_type = drop_type__content_type;
execute ''drop table '' || v_table_name || '' cascade'';
end if;
PERFORM acs_object_type__drop_type(drop_type__content_type, ''f'');
return 0;
end;' language 'plpgsql';
select content_folder__unregister_content_type(-100,'mfp_note','t');
select content_type__drop_type(
'mfp_note',
't',
't'
);
Sorry for the long posting ;). Comments are appreciated, I am not sure this is correct but as far as I checked all the references to mfp_notes are gone now.
