pg_end_copy() syncs the PostgreSQL frontend (usually a web server process) with the PostgreSQL server after doing a copy operation performed by pg_put_line(). pg_end_copy() must be issued, otherwise the PostgreSQL server may get out of sync with the frontend and will report an error. Siker esetén TRUE értékkel tér vissza, ellenkező esetben FALSE értéket ad.
For further details and an example, see also pg_put_line().
