The following bug has been logged on the website:
Bug reference: 13445
Logged by: Brent Douglas
Email address: brent(dot)n(dot)douglas(at)gmail(dot)com
PostgreSQL version: 9.4.4
Operating system: docs only
Description:
Section 8.15.1 is slightly missleading regarding array dimensionality as the
first example and following comment both read like array declarations in
many programming languages where [] is a single dimensional array and [][]
is a two dimensional array while having different semantics.
To make it more obvious that arrays do not have dimensions the section
stating this could be moved before the example table sal_emp.
The words "one-dimensional" and "two-dimensional" in the comment on the
sal_emp example table could also be removed.

Well, it's a little odd because while dimensionality is not enforced
when defining columns, it does have an effect when accessing values. I
am not sure that mentioning things in the opposite order would help as
we have to define dimensionality for us later.
