Wrappers

Wrappers is a development framework for Postgres Foreign Data Wrappers (FDW), written in Rust. Its goal is to make Postgres FDW development easier while keeping Rust language's modern capabilities, such as high performance, strong types, and safety.

Wrappers is also a collection of FDWs built by Supabase. We currently support the following FDWs, with more under development:

Warning

Restoring a logical backup of a database with a materialized view using a foreign table can fail. For this reason, either do not use foreign tables in materialized views or use them in databases with physical backups enabled.

Features

• Minimum interface and easy to implement.
• Support for rich data types.
• Support both sync and async backends, such as RDBMS, RESTful APIs, flat files and etc.
• Built on top of pgrx, providing higher level interfaces, without hiding lower-level C APIs.
• WHERE, ORDER BY, LIMIT pushdown are supported.

Documentation

• Usage Docs
• Developer Docs (docs.rs)

Installation

Wrappers is a pgrx extension, you can follow the pgrx installation steps to install Wrappers.

Basically, run below command to install FDW after pgrx is installed. For example,
