On files of that size they're a lot nicer than an interactive editor.
It's not like you need to find space on the disk for an edited copy:
(
echo "copy table_name from stdin other_parameters; "
cat bigfile | sed script_or_scriptfile
echo '\\.'
) | psql connection_parameters

The copy command is optimised and intended for use with data that is
known to be good, or atleast acceptable to the database.
