For next month, I'm scheduling 2 or 3 discussions of Matthias van de Meent's talk, Improving scalability; Reducing overhead in shared memory, given at 2025.pgconf.dev (talk description here). If you're interested in joining us, please sign up using this form and I will send you an invite to one of the sessions. Thanks to Matthias for agreeing to attend the sessions, and to Melanie Plageman for agreeing to serve as host. (I normally host, but am taking a month off. We will also skip December due to the end-of-year holidays.)
