I just ran this quick test in HEAD: alvherre=# create table study (id int primary key); NOTICE: CREATE TABLE / PRIMARY KEY creará el índice implícito «study_pkey» para la tabla «study» CREATE TABLE alvherre=# insert into study select a from generate_series(1, 1000000) as a; INSERT 0 1000000 alvherre=# create table studyform (id int primary key, study_id int not null references study); NOTICE: CREATE TABLE / PRIMARY KEY creará el índice implícito «studyform_pkey» para la tabla «studyform» CREATE TABLE alvherre=# insert into studyform select a, 1 + a * random() from generate_series(1, 100000) a; INSERT 0 100000
and was very surprised to see that the foreign key is marked as NOT VALID: alvherre=# \d studyform Tabla «public.studyform» Columna │ Tipo │ Modificadores ──────────┼─────────┼─────────────── id │ integer │ not null study_id │ integer │ not null Índices: "studyform_pkey" PRIMARY KEY, btree (id) Restricciones de llave foránea: "studyform_study_id_fkey" FOREIGN KEY (study_id) REFERENCES study(id) NOT VALID Is this really intended? -- Álvaro Herrera <alvhe...@alvh.no-ip.org> -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
