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
