Tags: rust postgresql database extensions development

Install: brew install pgrx

About:
Pgrx is a Rust framework designed for building Postgres extensions entirely in Rust, eliminating the need for C code. It provides a safe and ergonomic API for interacting with Postgres internals, managing SQL generation, and running tests. This tool significantly lowers the barrier to entry for creating high-performance, memory-safe database extensions.

Key Features:

Write Postgres extensions in safe Rust
Automatic SQL generation from Rust code
Integrated testing framework for extensions
Supports Postgres 10 through 16

Use Cases:

Developing custom data types and operators for PostgreSQL
Creating high-performance functions and aggregations
Building secure extensions with Rust's memory safety guarantees

Alternatives:

C extensions – Pgrx offers memory safety and easier build processes compared to traditional C development.
PL/Rust – Pgrx compiles to native loadable extensions, whereas PL/Rust runs stored procedures within the database engine.
