The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/9.6/static/view-pg-timezone-names.html
Description:

With regard to documentation page:

https://www.postgresql.org/docs/current/static/view-pg-timezone-names.html

Testing:

SELECT name, abbrev, utc_offset, is_dst FROM pg_catalog.pg_timezone_abbrevs
;

... produces the error 

ERROR:  column "name" does not exist
LINE 1: SELECT name, abbrev, utc_offset, is_dst FROM pg_timezone_abb...

Apparently, the column "name" isn't there any more.

SELECT * FROM pg_catalog.pg_timezone_abbrevs LIMIT 1;

produces

abbrev | utc_offset | is_dst
:----- | :--------- | :-----
ACDT   | 10:30:00   | t     

Either the table (or view) is lacking a column, or the documentation is
wrong. 

Tested on PostgreSQL 9.6.2 at

The documentation page you've referred to is for pg_timezone_names,
not pg_timezone_abbrevs.

The page for pg_timezone_abbrevs doesn't mention a "name" column:
https://www.postgresql.org/docs/current/static/view-pg-timezone-abbrevs.html
