Neues vom PostgreSQL Planet

My first thought seeing a temporal join in 2008 was, “Why is this query so complex?” The company I was at relied heavily on database queries, as it was a CRM and student success tracking system for colleges and universities. The query returned a filtered list of users and their last associated record from a second table. The hard part about the query isn’t returning the last timestamp or even performing joins, it’s returning only their last associated record from a second table.

PostgreSQL and NUMA, part 1 of 4

This series covers the specifics of running PostgreSQL on large systems with many processors. My experience is that people spend months often learning the basics when confronted with the problem. This series tries to dispel these difficulties by providing a clear background into the topics in question. The hope is that future generations of database engineers and administrators don’t have to spend months figuring things out through trial and error.
