Re: Duplicate data even with primary keys enabled

Hello Jakobs,

I have provided the sample create table and inserts that we are observing. 

CREATE TABLE IF NOT EXISTS "TEST"

(
    "COL1" character varying(9) COLLATE pg_catalog."default" NOT NULL,
    "COL2" character varying(30) COLLATE pg_catalog."default" NOT NULL,
    "COL3" character varying(30) COLLATE pg_catalog."default" NOT NULL,
    "COL4" numeric(10,0) NOT NULL,
    "COL5" character varying(12) COLLATE pg_catalog."default" NOT NULL,
    "COL6" character varying(12) COLLATE pg_catalog."default" NOT NULL,
    CONSTRAINT test_pk PRIMARY KEY ("COL1", "COL2", "COL3")
)

CREATE UNIQUE INDEX IF NOT EXISTS "TEST_UNIQUE"
    ON "TEST" USING btree
    ("COL1" COLLATE pg_catalog."default" ASC NULLS LAST, "COL2" COLLATE pg_catalog."default" ASC NULLS LAST, "COL3" COLLATE pg_catalog."default" ASC NULLS LAST);

CREATE INDEX IF NOT EXISTS "TEST_INDEX"
    ON "TEST" USING btree
    ("COL1" COLLATE pg_catalog."default" ASC NULLS LAST, "COL3" COLLATE pg_catalog."default" ASC NULLS LAST);

We already defined COL1, COL2, COL3 as primary keys, but still as you see above in the table output, the first 2 rows has exactly same combination for those 3 rows.
