Thread: Cluster table

I’m have this table :

CREATE TABLE "ITerp"."Dok" (

  "id_dok" INTEGER DEFAULT "AutoIncGet"('Dok'::text) NOT NULL,

  "sifvrste" CHAR(3) NOT NULL,

    REFERENCES "ITerp"."VrstaDok"("sifvrsta")

    ON DELETE RESTRICT

    ON UPDATE RESTRICT

    NOT DEFERRABLE

) WITHOUT OIDS;

CREATE UNIQUE INDEX "broj_idx_D" ON "ITerp"."Dok"

  USING btree ("sifvrste", "broj", "id_komitent", "id_objekat1");

CREATE INDEX "cluster_idx_dok" ON "ITerp"."Dok"

  USING btree ("id_komitent", "sifvrste", "datum", "broj", "id_dok");

CREATE INDEX "datum_idx_Dok" ON "ITerp"."Dok"

  USING btree ("datum");

CREATE UNIQUE INDEX "fakbroj_idx" ON "ITerp"."Dok"

  USING btree ("id_komitent", "sifvrste", (btrim((fakbroj)::text)))

  WHERE (((((sifvrste = 'OTP'::bpchar) OR (sifvrste = 'FAK'::bpchar)) OR (sifvrste = 'PFK'::bpchar)) OR (sifvrste = 'AVU'::bpchar)) OR (sifvrste = 'AVS'::bpchar));

CREATE INDEX "idtoken_idx" ON "ITerp"."Dok"

  USING btree ("idtoken");

CREATE INDEX "komitentD_idx" ON "ITerp"."Dok"

  USING btree ("id_komitent");

CREATE INDEX "objekat1D_idx" ON "ITerp"."Dok"

Table is physically ordered by primary key. I try to cluster table with :

CLUSTER cluster_idx_dok" ON "ITerp"."Dok" ;

but Table is still physically ordered by primary key. Why table is not reordered by index?
