Hello Bill,
while updating to 1.6 did you get some errors like that:
psql:database_schema_15-16.sql:105: ERROR: constraint
"community2collection_collection_id_fkey" of relation
"community2collection" does not exist
ALTER TABLE
psql:database_schema_15-16.sql:108: ERROR: constraint
"community2community_child_comm_id_fkey" of relation
"community2community" does not exist
ALTER TABLE
psql:database_schema_15-16.sql:111: ERROR: constraint
"collection2item_item_id_fkey" of relation "collection2item" does not exist
If so, inspect your database and use the references for the foreign keys
to delete them, e.g::
psql [YourDBName]
\d [TableName]
will show you the foreign keys, e.g.:
\d community2collection
Table "public.community2collection"
Column | Type | Modifiers
---------------+---------+-----------
id | integer | not null
community_id | integer |
collection_id | integer |
Indexes:
"community2collection_pkey" PRIMARY KEY, btree (id)
"community2collection_collection_id_idx" btree (collection_id)
"community2collection_community_id_idx" btree (community_id)
Foreign-key constraints:
"$1" FOREIGN KEY (community_id) REFERENCES community(community_id)
"$2" FOREIGN KEY (collection_id) REFERENCES collection(collection_id)
In that case you got to run:
ALTER TABLE collection2item DROP CONSTRAINT "$2";
ALTER TABLE community2community DROP CONSTRAINT "$2";
ALTER TABLE community2collection DROP CONSTRAINT "$2";
The reason for this is:
In Step 7 Update the database it can happen that not all the commands in
the database_schema_15-16.sql are executed properly.
The commands to drop foreign keys:
ALTER TABLE collection2item DROP CONSTRAINT collection2item_item_id_fkey;
ALTER TABLE community2community DROP CONSTRAINT
community2community_child_comm_id_fkey;
ALTER TABLE community2collection DROP CONSTRAINT
community2collection_collection_id_fkey;
assume that the keys got default names, whereas depending on the
database version and operating system on which your instance started,
they can have no names and just be counted internally.
If you got no names or other names the script will skip the commands,
with the above mentioned ERROR.
This will lead to errors running DSpace as now 2 contraints exist and
one is unable to delete items, collections etc.
Although the documentation states Postgres 7.3/7.4 or higher as
prerequisite, consider updating to a new (8.4 or higher) version of
postgres, as the support for even 8.2 will end in December 2010, see
http://jira.dspace.org/jira/browse/DS-618
Hope that helps
