Gemini CLIAbout this skill
Migrate a Ruby on Rails application's primary database from MySQL to PostgreSQL — schema upgrades (JSON to JSONB for queryability, ENUMs to native types or check constraints, TINYINT to BOOLEAN, case-sensitivity changes), data export/import via pgloader, the dual-write cutover pattern, the gem switch (mysql2/trilogy to pg), Rails-side caveats. Use when migrating from MySQL to Postgres, the user mentions pgloader, JSONB upgrade, ENUM migration, TINYINT to BOOLEAN, or asks how to move a Rails app to Postgres.
