OpenAI experienced this with ChatGPT: A single query joining 12 tables caused multiple high-severity production incidents. Complex multi-table joins are a common scaling bottleneck they can spike planning time, consume excessive resources, and create unpredictable performance. Understanding how PostgreSQL's optimizer...]]></description><link>https://www.datacloudgaze.com/post/understanding-postgresql-join-optimization-a-deep-dive</link><guid isPermaLink="false">697584df42f7501825e0452a</guid><category><![CDATA[PostgreSQL Migration]]></category><category><![CDATA[PostgreSQL]]></category><pubDate>Sun, 25 Jan 2026 08:16:15 GMT</pubDate><dc:creator>Deepak Mahto</dc:creator></item><item><title><![CDATA[PostgreSQL Timeout Parameters: Your Database’s Self-Defense System]]></title><description><![CDATA[(Inspired by OpenAI’s PostgreSQL scale challenges) When OpenAI shared their engineering journey of scaling PostgreSQL to support massive workloads, one insight quietly stood out: It’s also common to find long-running idle queries in PostgreSQL. Configuring timeouts like idle_in_transaction_session_timeout is essential to prevent them from blocking autovacuum. At first glance, this might sound like a small operational detail. But in reality, it points to a much bigger truth about how...]]></description><link>https://www.datacloudgaze.com/post/postgresql-timeout-parameters-your-database-s-self-defense-system</link><guid isPermaLink="false">6975c1c4e389f5384b737a8a</guid><category><![CDATA[PostgreSQL]]></category><category><![CDATA[PostgreSQL Migration]]></category><pubDate>Sat, 24 Jan 2026 18:30:00 GMT</pubDate><enclosure url="https://static.wixstatic.com/media/5b8722_c2589ab56a6d4f81ac1c29534559af4d~mv2.png/v1/fit/w_1000,h_1000,al_c,q_80/file.png" length="0" type="image/png"/><dc:creator>Deepak Mahto</dc:creator></item><item><title><![CDATA[Oracle to PostgreSQL DDL: Data Types, Partitions &#38; More]]></title><description><![CDATA[Migrating from Oracle to PostgreSQL?
