There's your problem. I'm pretty sure the keyword STRICT isn't valid there. It probably gets interpreted as a column name.


​No, its a sanity check/assertion.  If that trips its because there is no company having a value of NEW.id on the public.companies table.  If that is OK then remove the STRICT but if you are indeed expecting a record to be present and it is not it is correctly telling you that there is a problem in the data.  Namely that said company needs to be added to the table.

Taking off the "STRICT", the errors were gone. But still, it's not working. Please have a look below. 


If I use the other table:

CREATE TABLE public.company_seqs
(company_id BIGINT NOT NULL,
last_seq BIGINT NOT NULL DEFAULT 1000,
CONSTRAINT company_seqs_pk PRIMARY KEY (company_id)
);

It works fine.. the problem is when I try to use the companies table.. which is already there and I just add another column named: client_code_increment

haven't found the problem yet...
