Dynamic Table Partitioning in Postgres

The new partitioning scheme allows for efficient querying, data storage, and retrieval of chat messages. It uses a composite primary key and foreign keys to ensure data consistency and scalability. The dynamic table partitioning approach enables the creation of child tables with a specified range of dates, allowing for incremental data loading and attachment to the parent table without downtime. The `load_chats_partitions` procedure demonstrates how to create, copy, index, and attach new partitions, ensuring seamless integration into the existing database structure.
