I have applied the following patch:
---------------------------------------------------------------------------
Change psql \copy stdin/stdout to read from command input/output.
Add pstdin/pstdout to read from psql's stdin/stdout.
BACKWARD INCOMPATIBLE CHANGE

! For <literal>\copy <replaceable
class="parameter">table</replaceable> from <replaceable
! class="parameter">filename</replaceable></literal> operations,
! <application>psql</application> adds the option of using a
! hyphen instead of <replaceable
! class="parameter">filename</replaceable>. This causes
! <literal>\copy</literal> to read rows from the same source that
! issued the command, continuing until <literal>\.</literal> is
! read or the stream reaches <acronym>EOF</>. This option is
! useful for populating tables in-line within a SQL script file.
! In contrast, <literal>\copy from stdin</> always reads from
! <application>psql</application>'s standard input.

- Note the difference in interpretation of
- <literal>stdin</literal> and <literal>stdout</literal> between
- <literal>\copy</literal> and <command>COPY</command>.
- In <literal>\copy</literal> these always
- refer to <application>psql</application>'s input and output
- streams. In <command>COPY</command>, <literal>stdin</literal> comes
- from wherever the <command>COPY</command> itself came from (for
- example, a script run with the <option>-f</option> option), while
- <literal>stdout</literal> refers to the query output stream (see
- <command>\o</command> meta-command below).
