The PostgreSQL Funds Group may commission gifts for contributors recognized for a major release. The Funds Group makes an effort to contact everyone, but, nevertheless, people get missed. This page describes those gifts and links to the acknowledgements of the release to see if you are to receive a gift and how to inquire.
Please contact the team in charge of distribution at contributor-gifts(at)postgresql(dot)org with any questions. Please also send a mailing address, formatted as if being printed for a label, for us to send the gift to when claiming a gift. Even if you have received a gift previously, it would be good to let us know whether your address has changed.
