psql has a -q / --quiet option (environment variable QUIET). pg_restore does not have a quiet option. Is there any way to make pg_restore not verbosely show the SQL commands that it's executing?
# e.g., here's the verbose output that I don't want to see:
$ pg_restore --cluster 8.4/mycluster mycluster.dump
---- PostgreSQL database dump
--
SET statement_timeout = 0;SET client_encoding = 'UTF8';
SET standard_conforming_strings = off;SET check_function_bodies = false;
...
--
-- Name: data_src; Type: TABLE; Schema: public; Owner: postgres; Tablespace:--
CREATE TABLE data_src (
...
The question seems to imply that pg_restore is executing these SQL commands and you wouldn't want to see them in the output. But outputting them is what it's only supposed to do.
pg_restore has two modes of operation, with or without connecting to a database. When it's called without a database (-d option) as shown in the question:
$ pg_restore --cluster 8.4/mycluster mycluster.dump
then its sole purpose is to output a set of SQL commands in plain text that should be fed to an SQL interpreter to restore the database. Those SQL commands form a coherent set without any concept of verbosity, and they are not executed by pg_restore itself. They're generally redirected into a file for later execution or piped into psql for immediate execution.
