Hi,
Thanks for your reply. It is automatic, my app don’t creates ID, it delegates it to the DB. I am using Ruby on Rails app, where we use Postgresql.
docking_dev=# \d chinese_price_infos;
Table "public.chinese_price_infos"
Column | Type | Collation | Nullable | Default
-------------+-----------------------------+-----------+----------+-------------------------------------------------
id | integer | | not null | nextval('chinese_price_infos_id_seq'::regclass)
created_at | timestamp without time zone | | |
updated_at | timestamp without time zone | | |
item_code | character varying(255) | | |
description | character varying(255) | | |
unit | character varying(255) | | |
price_cents | integer | | |
uuid | uuid | | | uuid_generate_v4()
company_id | uuid | | |
Indexes:
"chinese_price_infos_pkey" PRIMARY KEY, btree (id)
"index_chinese_price_infos_on_company_id" btree (company_id)
Thanks,
Arup Rakshit

However, it sounds as if something in the application code may be causing problems.... For example, is something generating id values without reference to the sequence?
