-dbt uses an adapter-plugin pattern to extend support to different databases, warehouses, query engines, etc. For testing and development purposes, the dbt-postgres plugin lives alongside the dbt-core codebase, in the [`plugins`](plugins) subdirectory.

 Each adapter is a mix of python, Jinja2, and SQL. The adapter code also makes heavy use of Jinja2 to wrap modular chunks of SQL functionality, define default implementations, and allow plugins to override it.

 ### Notes
 
-- **Adapters:** Is your issue or proposed code change related to a specific [database adapter](https://docs.getdbt.com/docs/available-adapters)? If so, please open issues, PRs, and discussions in that adapter's repository instead. The sole exception is Postgres; the `dbt-postgres` plugin lives in this repository (`dbt-core`).
+- **Adapters:** Is your issue or proposed code change related to a specific [database adapter](https://docs.getdbt.com/docs/available-adapters)? If so, please open issues, PRs, and discussions in that adapter's repository instead.
 - **CLA:** Please note that anyone contributing code to `dbt-core` must sign the [Contributor License Agreement](https://docs.getdbt.com/docs/contributor-license-agreements). If you are unable to sign the CLA, the `dbt-core` maintainers will unfortunately be unable to merge any of your Pull Requests. We welcome you to participate in discussions, open issues, and comment on existing ones.
 - **Branches:** All pull requests from community contributors should target the `main` branch (default). If the change is needed as a patch for a minor version of dbt that has already been released (or is already a release candidate), a maintainer will backport the changes in your PR to the relevant "latest" release branch (`1.0.latest`, `1.1.latest`, ...). If an issue fix applies to a release branch, that fix should be first committed to the development branch and then to the release branch (rarely release-branch fixes may not apply to `main`).
-- **Releases**: Before releasing a new minor version of Core, we prepare a series of alphas and release candidates to allow users (especially employees of dbt Labs!) to test the new version in live environments. This is an important quality assurance step, as it exposes the new code to a wide variety of complicated deployments and can surface bugs before official release. Releases are accessible via pip, homebrew, and dbt Cloud.

+Code can be merged into the current development branch `main` by opening a pull request. If the proposal looks like it's on the right track, then a `dbt-core` maintainer will triage the PR and label it as `ready_for_review`. From this point, two code reviewers will be assigned with the aim of responding to any updates to the PR within about one week. They may suggest code revision for style or clarity, or request that you add unit or integration test(s). These are good things! We believe that, with a little bit of help, anyone can contribute high-quality code. Once merged, your contribution will be available for the next release of `dbt-core`.
 
 Automated tests run via GitHub Actions. If you're a first-time contributor, all tests (including code checks and unit tests) will require a maintainer to approve. Changes in the `dbt-core` repository trigger integration tests against Postgres. dbt Labs also provides CI environments in which to test changes to other adapters, triggered by PRs in those adapters' repositories, as well as periodic maintenance checks of each adapter in concert with the latest `dbt-core` code changes.
 
 Once all tests are passing and your PR has been approved, a `dbt-core` maintainer will merge your changes into the active development branch. And that's it! Happy developing :tada:

-# Adapters README
-
-The Adapters module is responsible for defining database connection methods, caching information from databases, how relations are defined, and the two major connection types we have - base and sql.
-
-# Directories
-
-## `base`
-
-Defines the base implementation Adapters can use to build out full functionality.
-
-## `sql`
-
-Defines a sql implementation for adapters that initially inherits the above base implementation and  comes with some premade methods and macros that can be overwritten as needed per adapter. (most common type of adapter.)
-
-# Files
-
-## `cache.py`
-
-Cached information from the database.
-
-## `factory.py`
-Defines how we generate adapter objects
-
-## `protocol.py`
-
-Defines various interfaces for various adapter objects. Helps mypy correctly resolve methods.
-
-## `reference_keys.py`
-
-Configures naming scheme for cache elements to be universal.

-## Base adapters
-
-### impl.py
-
-The class `SQLAdapter` in [base/imply.py](https://github.com/dbt-labs/dbt-core/blob/main/core/dbt/adapters/base/impl.py) is a (mostly) abstract object that adapter objects inherit from. The base class scaffolds out methods that every adapter project usually should implement for smooth communication between dbt and database.
-
-Some target databases require more or fewer methods--it all depends on what the warehouse's featureset is.
-
-Look into the class for function-level comments.

-# RelationConfig
-This package serves as an initial abstraction for managing the inspection of existing relations and determining
-changes on those relations. It arose from the materialized view work and is currently only supporting 
-materialized views for Postgres and Redshift as well as dynamic tables for Snowflake. There are three main
-classes in this package.
-
-## RelationConfigBase
-This is a very small class that only has a `from_dict()` method and a default `NotImplementedError()`. At some
-point this could be replaced by a more robust framework, like `mashumaro` or `pydantic`.
-
-## RelationConfigChange
-This class inherits from `RelationConfigBase` ; however, this can be thought of as a separate class. The subclassing
-merely points to the idea that both classes would likely inherit from the same class in a `mashumaro` or
-`pydantic` implementation. This class is much more restricted in attribution. It should really only
-ever need an `action` and a `context`. This can be though of as being analogous to a web request. You need to
-know what you're doing (`action`: 'create' = GET, 'drop' = DELETE, etc.) and the information (`context`) needed
-to make the change. In our scenarios, the context tends to be an instance of `RelationConfigBase` corresponding
-to the new state.
-
-## RelationConfigValidationMixin
-This mixin provides optional validation mechanics that can be applied to either `RelationConfigBase` or
-`RelationConfigChange` subclasses. A validation rule is a combination of a `validation_check`, something
-that should evaluate to `True`, and an optional `validation_error`, an instance of `DbtRuntimeError`
-that should be raised in the event the `validation_check` fails. While optional, it's recommended that
-the `validation_error` be provided for clearer transparency to the end user.
