Hello,
I receive the following error when creating a foreign key between two partitioned tables.
ERROR: there is no unique constraint matching given keys for referenced table "par_log_file"
Here is my setup:
CREATE TABLE par_log_file (
par_file_id character varying(20) NOT NULL,
par_id character varying(64) NOT NULL
) PARTITION BY RANGE (par_file_id) ;
ALTER TABLE ONLY par_log_file
ADD CONSTRAINT plf_pk PRIMARY KEY (par_file_id);
--
CREATE TABLE par_log_definition (
par_file_id character varying(20) NOT NULL,
tif_seq_nmbr bigint NOT NULL,
name_25 character varying(255)
) PARTITION BY RANGE (par_file_id) ;
ALTER TABLE ONLY par_log_definition
ADD CONSTRAINT pld_pk PRIMARY KEY (par_file_id, tif_seq_nmbr);
CREATE INDEX pld_idx ON par_log_definition USING btree (par_file_id);
ALTER TABLE par_log_definition
ADD CONSTRAINT pld_fk FOREIGN KEY (par_file_id) REFERENCES par_log_file(par_file_id);

CREATE INDEX pld_idx ON par_log_definition USING btree (par_file_id);
ALTER TABLE par_log_definition
ADD CONSTRAINT pld_fk FOREIGN KEY (par_file_id) REFERENCES par_log_file(par_file_id);
Version Postgres 13.13
Any help would be appreciated/
