Contribute to PostgreSQL by Testing

PGDay Lowlands invites the community to contribute to the next PostgreSQL major version

PostgreSQL 18 Beta 2 was released on the 17th of July. We invite you to test it and give your feedback to us and to the PostgreSQL developers before the official release.

What’s in for you?

We will add your name to the Wall of Testers, where we list all the participants of this initiative, so that your contribution is visible.

In addition to the glory of being listed in the Wall of Testers, on the 29th of August, PGDay Lowlands will raffle a free ticket to the event

How to participate?

Download, install, test, report.

  • Download and install PostgreSQL 18 Beta 2. See instructions at the PostgreSQL 18 Beta 2 page.
  • Test your own application trying to spot anything that doesn’t work. If you can compare performance of your application running on PostgreSQL 17 vs PostgreSQL 18 even better. Be as creative as you want with the test. That's the best way to find bugs.
  • If you don’t have an application, you can create ad hoc tests to verify and study new functionality (partitioning, indexes, replication, etc), or run pgbench, HammerDB or any other generic tool.
  • More ideas on testing can be found on the wiki
  • Report your test by sending an email to team@pgday.nl using the format explained in the wiki. Reporting success is also a valid test. We are interested in knowing how confident we are in the new release, and sharing which applications are ready to upgrade can also be useful to other users.

    IMPORTANT: If you spot a bug or a performance issue, please send also an email to the psql-bugs or psql-hackers mailing lists, as specified on the wiki

If you report more than one test, you increase your chances in the raffles. The raffle entries are per each test.

Timeline

Thursday 28th of August, 23:58 Rotterdam time (CEST) is the deadline to submit a test to participate in the raffle for the free ticket

29th of August, winner will be announced

More tests can still be submitted until the day of the official release.

The Wall of Testers will include all tests reported up to the official release of PostgreSQL 18

No elephants or tulips should be damaged during the testing process. Such a collateral effect will disqualify you from the Wall.
