    Is it possible to store historical data in PostgreSQL?
    Often, storing historical data with PostgreSQL is not the best solution – you don’t get to take advantage of the relational benefits of Postgres, and it’s a bit complicated to set up. However, when working with clients (or even for yourself), it’s a huge benefit to have all of a service’s data available through one interface in one query.

        To store historical data in Postgres, we are going to use two slightly more advanced tools: partitioning and triggers. Partitioning will allow us to separate our table into logical partitions, i.e. by month or week, while still allowing for queries among all rows.
