Acknowledged Individuals in the PostgreSQL Release Notes: 2026 Edition

I shared a chart, in 2022, showing where PostgreSQL contributor gifts are mailed to.  Here's an updated chart (click to zoom in.)

To quickly recap: the PostgreSQL community has been sending gifts to those who contribute directly to a new major release since version 12 came out.  There has now been 6 releases since then and version 19 is slated to be released this fall.

This chart can be construed as a gross indication of where code, testers, reviewers, bug reports, and documentation are coming from.  Thus it is interesting to see things like which countries have the most people, have been growing, or even to just see how many countries are involved with PostgreSQL.

But it's not an exact measure because this is based on the number of people who claim their gift.  Only about half the people in the release notes claim their gift.  It's not very easy to get in touch with everyone.  If you suspect you might be in the release notes or can help someone claim their gift, please take a look at the release notes (links can be found in the documentation or on the community wiki) and reach out to us by e-mail at contributor-gifts <at> postgresql.org to confirm.
