Bug reference:      11325
Logged by:          Thomas Landauer

PostgreSQL version: Unsupported/Unknown
Operating system:   Irrelevant
Description:

Two suggestions for "PostgreSQL 9.3.5 Documentation" (which is excellent in
general, by the way :-)

Capter 7.2.1.1

1) "Finally, NATURAL is a shorthand form of USING: it forms a USING list
consisting of all column
names that appear in both input tables."
Please clarify: All column names that appear in both input tables
(regardless of the SELECT clause), or all column names /listed in the SELECT
clause/ that appear in both input tables?

2) "with the exception that if ON is used there will be two columns a, b,
and c in the result"
Hard to understand. Suggestion:
"if ON is used, each column a, b, and c will appear twice in the result."

Cheers,
Thomas
