User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:5.0) Gecko/20100101 Firefox/5.0 Build Identifier:
A UNIQUE constraint on an attribute that references another table is not enforced.
Reproducible: Always
CREATE TABLE "test"."test" ("id" INT PRIMARY KEY );
CREATE TABLE "test"."test2" ("ref" INT REFERENCES "test"."test" , CONSTRAINT "unique" UNIQUE ("ref") );
INSERT INTO "test"."test" VALUES ('0');
INSERT INTO "test"."test2" VALUES ('0');
Two equal tuples in the database.
Insertion error when attempting to insert the second tuple.

confirmed, most likely the unique isn't respected because the foreign key

It works when created as follows:
create table test (id int primary key); create table test2 (id int unique references sys.test);
insert into test values (1); insert into test2 values (1);
insert into test2 values (1); SQLException:assert:INSERT INTO: UNIQUE constraint 'test2.test2_id_unique' violated insert into test2 values (2); SQLException:assert:INSERT INTO: FOREIGN KEY constraint 'test2.test2_id_fkey' violated
the following create statement also works correctly:
CREATE TABLE "test3" ( "id" INTEGER, CONSTRAINT "test3_id_unique" UNIQUE ("id"), CONSTRAINT "test3_id_fkey" FOREIGN KEY ("id") REFERENCES "sys"."test" ("id") );
If the two constraints are swapped in order (like the original bug) then the unique check appears to be skipped.

Date: 2011-07-13 21:37:10 +0200 From: @njnes
bug consisted of 2 problems 1) single column keys (with columns equal to some other key constrained), weren't created
inserting index values for multiple indices failed .
both are resolved
