# Description In issue #1290 folks report difficulty running migrations on an existing instance. The current migration table includes a `name` column, but no `id` column: ``` CREATE TABLE IF NOT EXISTS migrations ( name VARCHAR(255) PRIMARY KEY, executed_at TIMESTAMPTZ DEFAULT current_timestamp ); ``` By changing the `migrations.sh` script to use the `name` field, the migrations run as expected. ## Checklist before requesting a review - [x] My code follows the style guidelines of this project - [x] I have performed a self-review of my code
