PYTHON POSTGRESQL DRIVER
Types without binary support in the driver are unsupported in arrays and records.Backslash characters are being treated literally.

In our implementation of a data warehouse, we will be using a local Postgres server to store all our data in. Most importantly however, Postgres’s graphical user interface makes it too easy to provision and manage databases on the fly, something other database systems should take careful note of. Even though it is brandished as a structured database management system, it can also store non-structured data including but not limited to arrays and binary objects. PostgreSQL otherwise known as Postgres for short, is an open source relational database system that is more often than not the database of choice for developers due to its extended capabilities and relative ease of use. Perhaps in another article, we will implement the second point i.e. In addition we will create a dashboard where we can graphically interface with our warehouse to load, retrieve, mutate and visualize our data. In this tutorial we will be addressing the first and last points mentioned above by creating a data warehouse where we can store datasets, arrays and records into.
