title: How to suppress INFO messages when running psql scripts
body: <p>I'm seeing INFO messages when I run my tests and I <em>thought</em> that I had gotten rid of them by setting the client_min_messages PGOPTION.  Here's my command:  </p>
  
  <pre><code>
  PGOPTIONS='--client-min-messages=warning' \
            psql  -h localhost \
                  -p 5432 \
                  -d my_db \
                  -U my_user \
                  --no-align \
                  --field-separator '|' \
                  --pset footer \
                  --quiet \
                  -v AUTOCOMMIT=off \
                  -X \
                  -v VERBOSITY=terse \
                  -v ON_ERROR_STOP=1 \
                  --pset pager=off \
                  -f tests/test.sql \
                  -o "$test_results"
  </code></pre>
  
  <p>Can someone advise me on how to turn off the INFO messages?</p>
