postgresql copy update how?

There is a copy command that inserts data into tables from a file. Is there any analogue not for inserting, but for changing a record? Whether it is possible for example to use the trigger on insert for the temporary table in which there will be a check on existence of record on PK and to make update - how you think it is how effective? Is there something like insert .. on conflict update for the copy command?

Drive into a temporary table, and then use it to update the main table.
