Subject: [PATCH] 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.
Back-patch to 9.6 where effective_io_concurrency tablespace option was added.
