How to detect schema drift in CI and ensure the migration directory is up to date with the desired schema state - ORM, HCL, SQL, or any other schema definition?

A .env file is a simple text file used to store environment variables for applications. It helps developers manage configuration settings, such as database credentials, API keys, and other sensitive information, without hardcoding them into the source code. By using a .env file, developers can keep their codebase clean, secure, and easily configurable across different environments.

For developers who want to use .env files with Atlas, there are two ways users can do so through the standard Atlas HCL configuration file:

PostGIS is a spatial database extension for PostgreSQL. It adds support for geometric objects, enabling the processing of spatial data like points, lines, and polygons. After installing PostGIS, the GEOMETRY data type can be used to define tables that capture geo-spatial data, for example:

How can I install Atlas, and why is go install no longer supported?

Developers who use Atlas to run migrations using a golang-migrate directory format, may run into an errors like:

-> DROP TABLE `users`;
   Error 1051 (42S02): Unknown table 'public.users'

To include a PostgreSQL extension in your schema, there are a few configurations to be made to ensure the extension is properly applied.
