In this SO post, there are two answers that -combined together- provide a nice solution for successfully using ON CONFLICT. The example below, uses ON CONFLICT DO NOTHING;:

CREATE TEMP TABLE tmp_table 
(LIKE label INCLUDING DEFAULTS)
ON COMMIT DROP;

COPY tmp_table FROM 'full/file/name/here';

INSERT INTO main_table
SELECT *
FROM tmp_table
ON CONFLICT DO NOTHING;
