I have a strange issue (postgres 8.4) trying to insert old rows back
into the s_tbls table. A check on the primary key (n_id) between
s_tbl_import and s_tbls yields no matches, yet the index on s_tbls.n_id
yields an error when attempting to insert:
=> select n_id from s_tbl_import where n_id IN (
select n_id from s_tbls);
n_id
------
(0 rows)
=> insert into s_tbls (select * from s_tbl_import);
ERROR: duplicate key value violates unique constraint "s_tbls_pkey"
Table "s_tbls"
Column | Type |
Modifiers
------------------+-----------------------------+--------------------------------------------------------
n_id | integer | not null default
nextval('s_tbls_n_id_seq'::regclass)
dt_created | timestamp without time zone | default now()
dt_modified | timestamp without time zone | default now()
t_node | text |
...
Indexes:
"s_tbls_pkey" PRIMARY KEY, btree (n_id)
Thanks for any assistance
Rory
