    This function is useful it may not return a full non fatal error but you want to see if the query completes anyway.

    example

    <?PHP
    //connect to pg database
    // create PGSQL

    $PGSTAT = pg_result_status($PGSQL);//defaults to long

    //And run it through a check for example

    if(($PGSTAT == 1) || ($PGSTAT == 2)){
    // for query results;
    }else if(($PGSTAT == 3) || ($PGSTAT == 4)){
    // for copy results;
    }
    if((    $PGSTAT != 0) && ($PGSTAT != 5) && ($PGSTAT != 6) && ($PGSTAT != 7)){
    // your code;
    }else{
    // $ERRORS codes;
    }
    // This is worked the best for me so far I tried using
    // The command tag and I seem to still get an numeric result
    //example
    //$PGSTAT = pg_result_status($PGSQL, PGSQL_COMMAND_OK);
    // got something like tuples ok so I recommend just use default long
    ?>
    or use what ever condition check you feel fit

    If on "accident" your program passes pg_result_status a variable that is NOT a actual pg resource, it will return an empty string.
    (This is important to know if you want to make sure a pg resource is "good" before attempting some operation on it).

    The postgres docs say that PHP should never be able to return PGRES_NONFATAL_ERROR

    "A result of status PGRES_NONFATAL_ERROR will never be returned directly by PQexec or other query execution functions" http://www.postgresql.org/docs/current/static/libpq-exec.html

    Therefore you cannot use this function to check if this query produced a notice.
