Issue:
Add new Postgres versions in integration tests
- [x] I have searched the [issues](https://github.com/ent/ent/issues) of this repository and believe that this is not a duplicate.

## Summary 💡

As [the docs](https://entgo.io/docs/dialects/#postgresql) say
> PostgreSQL supports all the features that are mentioned in the [Migration](https://entgo.io/docs/migrate) section, and **it's being tested constantly on the following 5 versions: 11, 12, 13, 14 and 15**.

And it can be seen [in the CI code](https://github.com/ent/ent/blob/master/entc/integration/docker-compose.yaml#L130) that indeed it's only testing up to 15.

PostgreSQL is up to major version 17 now, so it'd be great to capture the newer versions in the integration tests.

## Motivation 🔦

We can see that there have been issues:
* https://github.com/ent/ent/issues/3971

Which could have likely been caught with proactive testing in CI.

And for a personal motivation, we are a bit scared to upgrade our own Postgres cluster beyond 15 due to the lack of testing on later versions.

Hints from issue comments:
@masseelch: Hey! The issue you are mentioning are in regards to the (legacy) migration engine. Ent no longer has its own migration engine, but is relying on [Atlas](https://atlasgo.io) to manage migrations. Atlas of course has support for all suported Postgres versions. 

@masseelch: I did add integration testing for PG16 and PG17 for the dialect tests. Hopefully this can reduce your concerns 🙏
