Re: Use or not record count on examples

There are lots of strange things related to this (... rows)
First, (0 rows) are completely useless. If no one record is shown, why do
we need that list ?

We could change (0 rows), like this one on dblink.sgml
SELECT * FROM dblink_get_notify();
notify_name | be_pid | extra
-------------+--------+-------
(0 rows)

We could change it to
SELECT * FROM dblink_get_notify();<returnvalue>no rows
returned</returnvalue>

Current version does not have these 19 rows as DOC says.
func.sgml
SELECT * FROM pg_ls_dir('.') WITH ORDINALITY AS t(ls,n);
...
(19 rows)

Show all settings counts 196 , but that is not true for current version.
show.sgml
SHOW ALL;
name | setting | description
-------------------------+---------+-------------------------------------------------
allow_system_table_mods | off | Allows modifications of the structure
of ...
.
.
.
xmloption | content | Sets whether XML data in implicit
parsing ...
zero_damaged_pages | off | Continues processing past damaged page
headers.
(196 rows)

Why do we need to show number of lines of explain ? I think all them could
be removed
explain.sgml
EXPLAIN SELECT * FROM foo WHERE i = 4;

QUERY PLAN
--------------------------------------------------------------
Index Scan using fi on foo (cost=0.00..5.98 rows=1 width=4)
Index Cond: (i = 4)
(2 rows)

Please let me know if you agree with some of these changes and I can create
a patch with that
