CloudNativePG part of LFX Mentorship - sign up as a mentee!
May 13, 2025 • 2 minutes
LFX Mentorship is a Cloud Native Computing Foundation mentorship platform that spans across the CNCF projects. More than 190 mentees have been accepted since the programs started in 2019, participating in 96 mentorship programs. We have proposed a project for the June cohort, and we’re looking for mentees to sign up and receive a stipend for their work!
Implementing “Declarative Management of PostgreSQL Foreign Data Wrappers”
The project we proposed aims to extend the CloudNativePG operator to support declarative configuration of foreign data wrappers through its Database custom resource (Upstream Issue). PostgreSQL supports the SQL/MED (Management of External Data) specification, enabling access to external data sources through standard SQL queries. These sources—known as foreign data—are accessed via foreign data wrappers (FDWs), which are libraries that handle the connection and data exchange with the external systems. A variety of FDWs are available for PostgreSQL. Of particular interest for this project is the postgres_fdw extension, which facilitates access to other PostgreSQL instances.
We’re looking forward to an elaborate design discussion in the upstream issue in CloudNativePG GitHub repository, involving mentors, maintainers, and the community. And ultimately of course, a fully working pull request implementing support for declarative foreign data wrappers, complete with reconciliation logic for the Database resource controller, Documentation, and automated tests integrated into the CI/CD pipeline.
