Where do we draw the lines?
At other tables.
Does Table DDL include all indexes?
Absolutely!
It should include constraints, clearly. I would not think it should have triggers.
Definitely triggers. And foreign keys.
Literally everything within the <<CREATE TABLE X(...);>>. (ie, no ALTER .. OWNER TO...)
ALTER statements, too. If CREATE TABLE ... LIKE ... { INCLUDING | EXCLUDING } { COMMENTS | COMPRESSION | CONSTRAINTS | DEFAULTS | GENERATED | IDENTITY | INDEXES | STATISTICS | STORAGE | ALL } can do it, then so should SHOW CREATE TABLE.

I can see the ALTER statements now. Which is why I asked.
I don't like the idea of including the trigger DDL, because that would never execute in a clean environment.
I would not be grumpy if trigger statements weren't included.
(I've never used a tool that tried to do that when I've wanted the DDL)
I can go either way on index creation.
Does this imply SQL SYNTAX like:
SHOW CREATE TABLE <table_name>
[ INCLUDING { ALL | INDEXES | SEQUENCES | ??? }]
[EXCLUDING { PK | FK | COMMENTS | STORAGE | } ]
[FOR {V11 | V12 | V13 | V14 | V15 }] ??
?
"FOR {V...}" is a complication too far, IMO. No one expects "pg_dump --schema-only" to have a --version= option, so one should not expect SHOW CREATE TABLE to have a "FOR {V...}" clause.
The goal for me is to open the discussion, and then CONSTRAIN the focus.
Personally, the simple syntax:
SHOW CREATE TABLE table1;
Should give me a create table command with the table attributes and the column attributes, FKs, PKs, Defaults. Etc.
But I would not expect it to generate index commands, etc.
