GSoC 2026: Call for Mentors, Project Ideas and Project Idea Reviews

Hey there!

Hi hackers,

We've been working on the PostgreSQL GSoC 2026 project ideas page and would love your input:

https://wiki.postgresql.org/wiki/GSoC_2026

As usual, GSoC is looking for volunteers ready to mentor projects. If any project interests you and you'd be willing to guide a contributor through it, please reach out. We especially need mentors with deep knowledge of the optimizer, storage layer, and monitoring infrastructure.

Have a project you've been wanting to see implemented? GSoC is a great opportunity to mentor someone through it. Add your ideas to the wiki or discuss them here or with the PostgreSQL GSoC org admins. The timeline is tight - contributor applications open March 16 and close March 31. Students will base their project proposals on ideas offered by this wiki page. Having well-defined projects with committed mentors significantly improves proposal quality.

Thanks Andrey! I just want to correct the dates. Ideas and potential
mentors (sic!) should be published before the February 3 - Mentoring
organization application deadline.
This will increase Postgres Org chances for being accepted as a
mentoring organization this year.
The number of potential mentors is even more important that ideas itself, IMHO.

We've researched past GSoC wikis and added several core project ideas that could use expert review:

1) Existing ideas carried forward
Several project ideas were brought over from previous years' "Still Relevant Ideas" lists. If you have expertise in these areas, please verify they're still relevant and appropriately scoped:
* Join Removal Based on Foreign Key Constraints
* Parallel GiST Index Build
* Per-Datatype TOAST Slicing Strategies
* ALTER TABLE SET LOGGED/UNLOGGED Performance
* Global Temporary Tables
* Regression Test Coverage Improvements
* Autonomous Transactions

2) New proposals
* B-tree Index Bloat Reduction (Page Merge). That's a bit controversial as a student work, we have serveral experimental ideas that need research.
* Monitoring Tools Performance (pg_stat_statements lock contention)
* Wait Event Coverage Improvements

Also you can contact gsoc-mentors@lists.postgresql.org if you'd like to get involved. Or we can just discuss things here.

Best regards, Andrey Borodin.

Hi,

I am a bit interested in joining the GSoC effort this year.

Do I understand it correctly that we can still add more projects and
improving the current ones up until March 16? And do you need more
mentors, projects proposal or help with any other thing?

No, the submission date for ideas was yesterday.

If you want to mentor - or being a backup - you have to select an
existing project. Note, that the current list will be trimmed, see the
rules on

https://wiki.postgresql.org/wiki/GSoC

so if you can help out that would be great.

Feel free to contact Pavlo and me off-list.

Thanks !

Best regards,
Jesper
