Use or not record count on examples

Sometimes we show that line "(4 rows)", but sometimes not.

Should we have a standard for it ? Should we add them all or remove them all ?

I think they are useless. Or maybe shown when no rows are returned.

datatype.sgml

  a   | char_length
------+-------------
 ok   |           2

 name | current_mood
------+--------------
 Moe  | happy
(1 row)

func.sgml

 a |  b
---+-----
 1 | foo
 2 |

 make  | model | sales
-------+-------+-------
 Foo   | GT    |  10
 Foo   | Tour  |  20
 Bar   | City  |  15
 Bar   | Sport |  5
(4 rows)

Or maybe when not all records are shown, like in planstats.sgml

 index |  values  | nulls | frequency | base_frequency
-------+----------+-------+-----------+----------------
     0 | {0, 0}   | {f,f} |      0.01 |         0.0001
     1 | {1, 1}   | {f,f} |      0.01 |         0.0001
   ...
    49 | {49, 49} | {f,f} |      0.01 |         0.0001
    50 | {50, 50} | {f,f} |      0.01 |         0.0001
   ...
    97 | {97, 97} | {f,f} |      0.01 |         0.0001
    98 | {98, 98} | {f,f} |      0.01 |         0.0001
    99 | {99, 99} | {f,f} |      0.01 |         0.0001
(100 rows)
