Here is a good one. I have three fields set for my primary key. Now I
thought that a primary key was unique, and dups can not be inserted.
CREATE TABLE "inventory" (
"stock" character varying(50) NOT NULL,
"inventory_type" character varying(20) DEFAULT 'unknown' NOT NULL,
"client_id" integer NOT NULL,
[...]
Constraint "inventory_pkey"
Primary Key ("stock", "inventory_type", "client_id")
);
and I insert into the db and get dups.
client_id | stock | inventory_type

Why did I get dups in my data?
PostgreSQL 7.1.3 on i686-pc-linux-gnu, compiled by GCC 2.95.4
Thanks.
