Description:

When trying to create a table, or to add a foreign key constraint to a
table, an error (see below) is produced. However, both tables are permanent
tables, and there are no temporary tables that I am aware of.

ERROR: constraints on permanent tables may reference only permanent tables

ALTER TABLE bnm.table1
    ADD CONSTRAINT id_fk FOREIGN KEY (bnm_id)
    REFERENCES bnm.table2 (id) MATCH SIMPLE
    ON UPDATE NO ACTION
    ON DELETE NO ACTION;
