I especially enjoyed these:<\/p>\n<\/div>\n<\/div>\n<div>\n<ul>\n<li>Keynote from Catherine Bouxin (Data Bene) \u2014 \u201cReduce energy usage: contributing towards a greener future while directly improving cost and performance.\u201d She highlighted how IT has become a huge consumer of energy, contributing to climate change\u2014and why every optimization matters. It\u2019s a topic not often discussed in the IT world and it drew a lot of attention from the audience.<\/li>\n<\/ul>\n<ul>\n<li>Robert Treat \u2014 \u201cVacuuming Large Tables: How Recent Postgres Changes Further Enable Mission Critical Workloads.\u201d He presented a scary real\u2011life scenario\u2014a vacuum failure turned into a steep learning opportunity\u2014and explained how to avoid transaction wraparound disasters on extremely high\u2011load systems.<\/li>\n<\/ul>\n<ul>\n<li>Mauricio Zambrano \u2014 \u201cPostgreSQL at the Square Kilometre Array Observatory.\u201d The SKAO is a massive global radio\u2011telescope project, gathering extreme amounts of data every second. Managing this unbelievable data flow with PostgreSQL on Kubernetes is truly a cosmic challenge.<\/li>\n<\/ul>\n<ul>\n<li>\u00c1lvaro Hern\u00e1ndez \u2014 \u201cPostgres \u00e0 la carte: dynamic container images with your choice of extensions.\u201d He presented a new approach to dynamic container images that lets users add whatever PostgreSQL extensions they need without maintaining special custom images for every combination.<\/li>\n<\/ul>\n<ul>\n<li>Sweta Vooda \u2014 \u201cBeyond Storage: Postgres as a Control Plane.\u201d This session reimagined what we can do with Postgres beyond just storing data. She showed patterns and ideas for building extensions that let PostgreSQL orchestrate external compute engines, offloading heavy workloads to specialized systems.<\/li>\n<\/ul>\n<ul>\n<li>On the second day, \u00c1lvaro Hern\u00e1ndez delivered the keynote \u201cWhich Postgres are you running?\u201d about why it\u2019s crucial to know the exact build of PostgreSQL you run. He discussed reproducible builds and SBOMs (Software Bill of Materials), and introduced a new idea for a more reliable solution.<\/li>\n<\/ul>\n<ul>\n<li>Grant Zhou \u2014 \u201cUniversal Database Synchronization with Modern Multi\u2011Connector Architecture.\u201d He introduced the SynchDB extension, which can perform CDC from multiple sources\u2014MySQL, SQL Server, and Oracle\u2014into PostgreSQL.<\/li>\n<\/ul>\n<ul>\n<li>C\u00e9dric Villemain \u2014 \u201cStats roll, baby, stats roll.\u201d He explained the new PACS framework for advanced PostgreSQL observability.<\/li>\n<\/ul>\n<ul>\n<li>And last but not least, Michael Meskes \u2014 \u201cFrom Code to Commerce: Open Source Business Models.\u201d A long\u2011time open\u2011source entrepreneur and founder of credativ, he offered thoughtful insights into business models from dual\u2011licensing to open\u2011core to newer cloud\/SaaS approaches, with pros and cons for each.<\/li>\n<\/ul>\n<p><a
