Since four years we work on a machine learning project in production, using Postgres as a database. We are sharing the problems we encountered and suggest possible solutions: how to keep track of the database usage from different components from a large codebase and detect bottlenecks, how to systematically profile queries duration and reduce downtime when the database is upgraded. We'll see a few simple ways to handle schema changes when ingesting data from outside and caching using files.
