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.db
pg_restore < /tmp/test.db
pg_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.

I have patched pg_restore to output the script contents if you restore
with -v:
pg_restore -v -d test /tmp/x
Patch attached. I will save this for 7.5.

I don't think it's a good idea to overload the -v switch with it. A
separate switch seems OK, but I don't quite get the point of this
functionality, actually.

Oh, OK. When I was testing, I didn't realize that pg_restore doesn't do
anything unless you specify the database via -d, but I see it in the
docs now:
pg_restore can operate in two modes: If a database name is
specified, the archive is restored directly into the
database. Otherwise, a script containing the SQL commands
necessary to rebuild the database is created (and written
to a file or standard output), similar to the ones created
by the pg_dump plain text format. Some of the options con-
trolling the script output are therefore analogous to
pg_dump options.
