Christophe Pettus: All Your GUCs in a Row: autovacuum_work_mem
autovacuum_work_mem sets the maximum memory each autovacuum worker may use for tracking dead tuple identifiers (TIDs) during a vacuum. Default is -1, which means “inherit from maintenance_work_mem.” Context is sighup. The parameter exists so that autovacuum’s memory consumption can be tuned indep…

Radim Marek: Strong views on PostgreSQL VIEWs
VIEWs should be the cleanest abstraction SQL, and therefore Postgres, has on offer. I love the concept. The promise of decoupling logical intent from physical storage is perfect on paper. In practice, few things in the database world trigger such a heated debate or carry as much historical baggage. VIEWs mix big promises with false hopes, and the promises rarely survive contact with production. The appeal is straightforward. Abstract "active customer" once and reuse it everywhere. Every query...
