Subject: Lack of possibility to specify CTAS TAM
Date: Wed, 31 Jul 2024 12:03:23 +0500
Message-ID: <CALdSSPgV8xXopOUBkvseVQTx7kNbd1w7++YCqvQaurMHdZ_=KQ@mail.gmail.com> (raw)

I have noticed $subj while working with other unrelated patches.
The question is, why there is no CREATE TABLE AS .... USING
(some_access_method)?
This feature looks straightforward, and lack of it is a bit of
inconsistency from my point of view.
Maybe there are some unobvious caveats with implementing it?
I have done a little research reading related threads [1][2], but
these do not address $subj, if i'm not missing anything.
Neither can I find an open CF entry/thread implementing this (Im
looking here http://cfbot.cputube.org/) .

The same storage specification feature can actually be supported for
CTAE (like CTAS but execute) and CREATE MATERIALIZED VIEW.

I can try to propose a POC patch implementing $subj if there are no objections
to having this functionality in the core.
