Backport 3/3 commits from #107367 on behalf of @ecwall.

/cc @cockroachdb/release


Fixes #107364

This changes the CREATE TABLE AS schema change job description to no longer incorrectly
include column types.
For example
CREATE TABLE movr.public.t2 (id INT8) AS SELECT * FROM movr.public.t;
becomes
CREATE TABLE movr.public.t2 (id) AS SELECT * FROM movr.public.t;

Release note (bug fix): Fix CREATE TABLE AS schema change job description SQL syntax.


Release justification: CTAS schema change job description fix.

Add the invalid type to the `type reference must implement NodeFormatter` error
to help with debugging.

Release note: None
Refactor `newTableDescIfAs` slightly to make it clear that `p.Defs` iteration
only happens if `p.Defs` is not empty.

Release note: None

Thanks for opening a backport.

Please check the backport criteria before merging:

  • Patches should only be created for serious issues or test-only changes.
  • Patches should not break backwards-compatibility.
  • Patches should change as little code as possible.
  • Patches should not change on-disk formats or node communication protocols.
  • Patches should not add new functionality.
  • Patches must not add, edit, or otherwise modify cluster versions; or add version gates.
If some of the basic criteria cannot be satisfied, ensure that the exceptional criteria are satisfied within.
  • There is a high priority need for the functionality that cannot wait until the next release and is difficult to address in another way.
  • The new functionality is additive-only and only runs for clusters which have specifically “opted in” to it (e.g. by a cluster setting).
  • New code is protected by a conditional check that is trivial to verify and ensures that it only runs for opt-in clusters.
  • The PM and TL on the team that owns the changed code have signed off that the change obeys the above rules.

Add a brief release justification to the body of your PR to justify this backport.

Some other things to consider:

  • What did we do to ensure that a user that doesn’t know & care about this backport, has no idea that it happened?
  • Will this work in a cluster of mixed patch versions? Did we test that?
  • If a user upgrades a patch version, uses this feature, and then downgrades, what happens?
