Обсуждение: pg_restore -d doesn't display output

Does anyone know why 'pg_restore -d' doesn't display the commands being
executed, like you see when you don't use '-d':
pg_dump -Fc test >/tmp/test.dbpg_restore < /tmp/test.dbpg_restore -d test < /tmp/test.db

The first pg_restore displays the commands, while the second does not.

The first sends a script to stdout (effectively equivalent to pg_dump
plain style).  The second sends the commands to a backend.

I would have expected there to be a --verbose option that would also echo
the commands to stderr, but it doesn't look like there's any support for
that in the code.

I don't understand why sending something to a backend should effect the
script output.
