   <function>pg_end_copy</function> syncs the PostgreSQL frontend
   (usually a web server process) with the PostgreSQL server after
   doing a copy operation performed by
   <function>pg_put_line</function>. <function>pg_end_copy</function>
   must be issued, otherwise the PostgreSQL server may get out of
   sync with the frontend and will report an error.
