Migrate a Laravel application's database from MySQL/MariaDB to PostgreSQL safely. Use when moving a Laravel app to Postgres, when Eloquent/queries behave differently after switching drivers, or when planning a MySQL->Postgres cutover. Covers the migration strategy (pgloader vs query-builder), the Laravel-specific behavior differences that silently break (case sensitivity, booleans, the id-sequence trap, raw SQL, GROUP BY strictness), and a verification checklist.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Laravel: MySQL -> PostgreSQL migration The data moves fine. What breaks is the assumptions your app baked in over the years, because **MySQL is forgiving and Postgres is strict**. Every place you leaned on MySQL being lenient is a bug waiting on the other side. Treat a migration as an *audit of your app's lazy assumptions*, not a data transfer. ## Step 0 - The one test that surfaces half the problems Before touching real data, point `php artisan migrate` at a **fresh empty Postgres database** and watch what throws. If every migration runs clean, your schema is genuinely database-agnostic. If it throws, you just found your MySQL-only assumptions for free. ```bash # .env pointed at an empty pgsql db php artisan migrate:fresh # does the schema even build on Postgres? ``` Do not delete MySQL the day you switch. Keep it running for days/weeks until you're sure - cutovers get reverted. ## Step 1 - Move the data (pick one) …

How to install
mdr add majdghithan/agent-skills/laravel-mysql-to-postgres@sha256:760a5dd3b94f5096The line at the top of this page pins the label git:20260729.b363e32, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
