hi.

attached patch is to make CREATE TABLE LIKE copy source relation
storage parameter
demo:

create table t(a text) with (fillfactor = 100, toast.vacuum_truncate=true);
create table t2(like t including storage parameter) with (parallel_workers = 3);

                                          Table "public.t2"
 Column | Type | Collation | Nullable | Default | Storage  |
Compression | Stats target | Description
--------+------+-----------+----------+---------+----------+-------------+--------------+-------------
 a      | text |           |          |         | extended |
  |              |
Access method: heap
Options: parallel_workers=3, fillfactor=100, toast.vacuum_truncate=true

of course, duplicate storage mention would result error,
for example:
create table t3(like t including storage parameter) with (fillfactor = 100);

Since we already support INCLUDING STORAGE, I’m not sure that
INCLUDING STORAGE PARAMETER is the right syntax to go with.
