title: Checking fillfactor setting for tables and indexes
body: <p>There is maybe some function to check the fillfactor for indexes and tables? I've tried already \d+  but have basic definition only, without fillfactor value:</p>
  
  <pre><code>        Index "public.tab1_pkey"
   Column |  Type  | Definition | Storage 
  --------+--------+------------+---------
   id     | bigint | id         | plain
  primary key, btree, for table "public.tab1"
  </code></pre>
  
  <p>For tables haven't found anything. If table was created with fillfactor other than default:</p>
  
  <pre><code>CREATE TABLE distributors (
      did     integer,
      name    varchar(40),
      UNIQUE(name) WITH (fillfactor=70)
  )
  WITH (fillfactor=70);
  </code></pre>
  
  <p>Then <code>\d+ distributors</code>shows non-standard fillfactor.</p>
  
  <pre><code>                            Table "public.distributors"                                                                                                                                        
   Column |         Type          | Modifiers | Storage  | Stats target | Description                                                                                                            
  --------+-----------------------+-----------+----------+--------------+-------------

   name   | character varying(40) |           | extended |              |

  Has OIDs: no
  Options: fillfactor=70
  </code></pre>
  
  <p>But maybe there is a way to get this value without parsing output?</p>
