Peter,

Thanks.  Our system was created using a 7.x version but we are currently 
running an 8.x version.  Now, on to the statistics!

Subject: Re: [Dspace-tech] Error when updating scheme from 1.5.2. to 1.6

Hi Dale,

I've run into that when upgrading instances during testathon. 1.5.2 -> 1.6rc1 | 
1.6rc2

I've had to comment out those lines, and I haven't noticed any issues. 
Especially since its dropping a constraint which doesn't exist.

Also, since I find it easier to just run a correct query as opposed to backup, 
run bad query, restore backup, ... I find it easier to wrap database upgrade 
scripts into a transaction so it either all works, or doesn't alter anything.

BEGIN;
whole bunch of db scripts
# ALTER TABLE community2collection DROP CONSTRAINT 
community2collection_collection_id_fkey;
# ALTER TABLE community2community DROP CONSTRAINT 
community2community_child_comm_id_fkey;
#ALTER TABLE collection2item DROP CONSTRAINT collection2item_item_id_fkey;
COMMIT;


I had asked this on the IRC #dspace back in December, and I think Mark Diggory 
had asked me what version of postgres I was using, if it was pre-postgres 8.x.

Our production server is 8.1.11, however initial install and previous upgrades 
would likely have been on an older version of pg.

Good morning,

We are attempting to upgrade our development instance to 1.6 and received the 
errors below when updating the schema.  Any suggestions as to the 
cause/correction?  Thanks.
