I believe that's how I started, not knowing any other way, but the pg_dump
utility spits things out in all the gory details!
Somewhere along the line the default value for the id field was lost. I at
first suspected it happened in the dump/restore cycle when I restored the
data back into 8.0 after dumping it with 8.2 but I reran that scenario and
something else happened: It would NOT restore back into 8.0 at all, so that
must not be what I actually did to get into the "lost default" situation.
Below is what 8.2 dumps out. 8.0 refuses imported that. I suppose if I had
originally edited the 8.2 dump data to "fix" this I might have gotten into
the mess I was in but I sure don't remember doing that.
8.2 dump data:
id integer DEFAULT nextval(('auth_id_seq'::text)::regclass) NOT NULL,
What 8.0 is happy with:
id integer DEFAULT nextval('vault_id_seq'::text) NOT NULL,
Bob
