For what it's worth, we have several unique constraints in the tables we replicate and I haven't seen this issue. --S -----Original Message----- From: slony1-general-bounces at lists.slony.info [mailto:slony1-general-bounces at lists.slony.info] On Behalf Of Thomas Spreng Sent: Tuesday, August 19, 2008 5:26 AM To: glynastill at yahoo.co.uk Cc: slony1-general at lists.slony.info Subject: Re: [Slony1-general] Random Duplicates Error On 19.

Yes, the primary key field uses a sequence: <sql> CREATE SEQUENCE records_id_seq INCREMENT 1 MINVALUE 1 MAXVALUE 9223372036854775807 START 624877670 CACHE 1; </sql> > And if so are they replicated? Yes, it's in the slony replication set. But the sql insert error is always caused by the constraint 'records_vendor_id_key' AFAIK, whose fields don't use any sequence. > Can you post the table definition? <sql> CREATE TABLE records ( id serial NOT NULL, vendor_id character varying NOT NULL, subvendor_id integer NOT NULL, destination character varying NOT NULL, departure_city character varying NOT NULL, departure_date date NOT NULL, duration integer NOT NULL, description text NOT NULL, price numeric(10,2) NOT NULL, price_inaccurate boolean NOT NULL DEFAULT false, adults character varying NOT NULL DEFAULT ''::character varying, children character varying NOT NULL DEFAULT ''::character varying, babies character varying NOT NULL DEFAULT ''::character varying, total_price numeric(10,2), url character varying NOT NULL, accomodation boolean NOT NULL, transport boolean NOT NULL, car boolean NOT NULL, offer_type integer, offer_id character varying, offer_name character varying, attributes character varying NOT NULL DEFAULT ''::character varying, location_id integer, vendor_rec_id character varying NOT NULL, vendor_group_id character varying NOT NULL, unlinked integer NOT NULL DEFAULT 0, created_on timestamp without time zone NOT NULL DEFAULT now(), modified_on timestamp without time zone NOT NULL DEFAULT now(), enabled boolean NOT NULL DEFAULT true, price_foreign numeric(10,2), currency_foreign character varying(3), CONSTRAINT records_pkey PRIMARY KEY (id), CONSTRAINT records_location_id_fkey FOREIGN KEY (location_id) REFERENCES locations (id) MATCH SIMPLE ON UPDATE CASCADE ON DELETE SET NULL, CONSTRAINT records_vendor_id_key UNIQUE (vendor_id, vendor_rec_id) ) WITH (OIDS=FALSE); ALTER TABLE records ALTER COLUMN id SET DEFAULT nextval('records_id_seq'::regclass); </sql> cheers, tom. _______________________________________________ Slony1-general mailing list Slony1-general at lists.slony.info http://lists.slony.info/mailman/listinfo/slony1-general
