Catch all error psql function exception : <p>I am writing an function with exception catching and ignoring. I want to catch all the exceptions and just ignore it. Is there anyway to catch all the exceptions and not individually?</p>

<pre><code>CREATE OR REPLACE FUNCTION ADD_TABLE_TO_ARCHIVE (a TEXT, b TEXT)
RETURNS INTEGER AS $SUCCESS$
DECLARE SUCCESS INTEGER;
BEGIN
    SUCCESS = 0;
    BEGIN
        UPDATE ARCHIVE_STATUS
        SET *****
        WHERE ***;
        SUCCESS = 1;
    EXCEPTION
        WHEN UNIQUE_VIOLATION 
        SUCCESS = 0;
    END;

   RETURN SUCCESS;
END;
$SUCCESS$ LANGUAGE plpgsql;
</code></pre>

<p>In place of unique exception, it should be any exception...</p>
