# POSTGRES_TO_GOMIGRATE

Simple script to prepare [gomigrate](https://github.com/golang-migrate/migrate) migration files from existing postgres database

1. Setup Postgres (we setup using docker-compose)

    ```bash

    # start postgres

    docker compose up -d

    # stop and clean postgres 

    docker compose down -v

    # execute initial database script

    PGPASSWORD=pass psql -h localhost -p 5434 -U user -d user -f initial_database.sql

    # postgres cli

    PGPASSWORD=pass psql -h localhost -p 5434 -U user -d user 

    ```

2. Generate migrations file (edit the script for different configs)

    ```bash

    # remove the previous generated files

    rm -rf migrations

    # run the script

    go run generate_migration.go

    ```

3. Test for GoMigrate (don't forget to clean your database before)

    ```bash

    # install gomigrate

    brew install golang-migrate

    # migrate database

    migrate -path migrations -database "postgresql://user:pass@localhost:5434/user?sslmode=disable" up

    # rollback database

    migrate -path migrations -database "postgresql://user:pass@localhost:5434/user?sslmode=disable" down

    ```
