Adding multiple Postgres databases to Hasura

The latest release of Hasura introduces support for multiple Postgres databases. This feature enables multi-tenant architecture and federated data graphs, allowing developers to maintain disparate systems in a unified ops platform. With this capability, teams can add existing databases to Hasura for observability, tracking, maintenance, and migrations within a single console. Additionally, it supports polyglot workloads by unifying various data structures and models into one back-end, leading to increased developer efficiency and operational improvements. Furthermore, multiple Postgres support facilitates the creation of federated graphs, enabling seamless communication across data sets without compromising performance or security.
