The following documentation comment has been logged on the website:
Page: https://www.postgresql.org/docs/9.6/static/sql-altertablespace.html
Description:
This page:
https://www.postgresql.org/docs/9.6/static/runtime-config-resource.html
Tell about effective_io_concurrency could be changed for a specific
tablespace and refer to this page:
https://www.postgresql.org/docs/9.6/static/sql-altertablespace.html
Who said "Currently, the only available parameters are seq_page_cost and
random_page_cost." and refer to them.
Option "effective_io_concurrency" is missing as I tried the following
command and it worked:
alter tablespace emet_temp set (effective_io_concurrency=50);
Cheers

Thanks for the report, this has been fixed recently by this commit and
will be available with 9.6.2:
commit: 4e344c2cf4ff00ca38ea0035bc137dab95fdd0c0
author: Fujii Masao <fujii@postgresql.org>
date: Sat, 17 Dec 2016 01:25:29 +0900
Add missing documentation for effective_io_concurrency tablespace option.
The description of effective_io_concurrency option was missing in ALTER
TABLESPACE docs though it's included in CREATE TABLESPACE one.
