JSON serialization using Serde Rust crates in Amazon RDS for PostgreSQL

This article explains how to use Serde Rust crates for JSON serialization in Amazon RDS for PostgreSQL, highlighting the capabilities of PL/Rust and PGRX.

• Demonstrates how to create custom JSON serialization functions in Rust within PostgreSQL
• Shows how to map PostgreSQL data types to Rust using PGRX
• Provides step-by-step instructions for setting up an RDS PostgreSQL instance with PL/Rust
• Explains how to use Serde and Serde_json crates to serialize custom data types
• Covers creating custom Rust structs that can be converted to JSON

The solution allows developers to efficiently create and manipulate JSON objects in PostgreSQL using Rust, overcoming previous limitations in JSON type handling.
