Description:

Running 9.4.6 and 9.4.7, I think I have encountered a bug with INCLUDING
STORAGE.

The CREATE TABLE syntax with INCLUDING STORAGE would seem to suggest that
storage options on the parent table (such as fillfactor) are copied to the
new child table, but this doesn't appear to work:

jnelson=# create table p (column1 integer not null) with (fillfactor = 70);
CREATE TABLE
jnelson=# \d+ p
Table "public.p"
Column | Type | Modifiers | Storage | Stats target | Description
---------+---------+-----------+---------+--------------+-------------
column1 | integer | not null | plain | |
Options: fillfactor=70

jnelson=# create table c (like p including storage);
CREATE TABLE
jnelson=# \d+ c
Table "public.c"
Column | Type | Modifiers | Storage | Stats target | Description
---------+---------+-----------+---------+--------------+-------------
column1 | integer | not null | plain | |
