Send us a contribution straight from the site

Tue, 15 Sep 2026 15:02:40 +0000

Until now, the only way to tell us about a contribution worth listing was email. There is now a form on the site instead.

You do not need an account, and you do not have to tell us who you are. Write the contribution in one box, in plain text or Markdown, and send it. If you would like us to be able to come back to you with a question, there is an optional line for your name and email address.

Many contributions to and for the PostgreSQL Project happen outside of writing code: talks, meetups, translations, patch reviews, mentoring, advocacy, documentation, event organisation. If you know of one, whether it is yours or somebody else's, we would like to hear about it.

Nothing is published automatically. Everything that comes in gets read by one of us first. Email still works, if you prefer it.
