Mig2Schema FAQs

Question 1

What is Mig2Schema?

Accepted Answer

Mig2Schema is a command-line interface (CLI) tool designed to extract the final database schema from PostgreSQL migration files. It runs your migrations in a temporary, isolated database instance to discover the resulting schema.

Question 2

How does Mig2Schema ensure safe schema extraction?

Accepted Answer

It leverages Testcontainers to spin up a new, temporary PostgreSQL database instance for each extraction. This isolated environment ensures that your local or production databases remain untouched, providing a safe way to analyze schema changes.

Question 3

What types of schema output can Mig2Schema provide?

Accepted Answer

Mig2Schema offers two main output modes: a human-readable 'info mode' for quick overviews and an 'extract mode' that generates full SQL DDL (Data Definition Language) statements. You can also choose between 'native' or 'pg_dump' providers for varying levels of detail, with 'pg_dump' providing more comprehensive DDL.

Question 4

Can Mig2Schema be integrated with AI development tools?

Accepted Answer

Yes, Mig2Schema functions as an MCP (Model Context Protocol) server. This allows AI tools, such as Claude Code, to seamlessly integrate and use Mig2Schema for automated database schema extraction and validation from your migration directories.

Question 5

What are the primary benefits of using Mig2Schema?

Accepted Answer

Mig2Schema simplifies the complex task of understanding and validating your PostgreSQL database schema, especially in projects with many migration files. It ensures an accurate and up-to-date representation of your database structure, aiding development, testing, and AI-driven code generation.
