<para>
<function>pg_put_line</function> sends a NULL-terminated string
to the PostgreSQL backend server. This is useful for example for
very high-speed inserting of data into a table, initiated by
starting a PostgreSQL copy-operation. That final NULL-character
is added automatically. Returns TRUE if successfull, FALSE
otherwise.
</para>
<note>
<para>
Note the application must explicitly send the two characters "\."
on a final line to indicate to the backend that it has finished
sending its data.
</para>
