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:

FDW Description Read Modify
HelloWorld A demo FDW to show how to develop a basic FDW.
BigQuery A FDW for Google BigQuery
Clickhouse A FDW for ClickHouse
Stripe A FDW for Stripe API
Firebase A FDW for Google Firebase
Airtable A FDW for Airtable API
S3 A FDW for AWS S3
Logflare A FDW for Logflare
Auth0 A FDW for Auth0
SQL Server A FDW for Microsoft SQL Server
Redis A FDW for Redis
AWS Cognito A FDW for AWS Cognito
Notion A Wasm FDW for Notion
Snowflake A Wasm FDW for Snowflake
Paddle A Wasm FDW for Paddle

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

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,
