PostgreSQL - memory management internals

Talk by Krishnakumar Ravi

PostgreSQL uses memory for several purposes such as caching data (buffer cache), supporting user scenarios like query processing (work mem), as managed resource for internal use (memory context) and more. We will look at how each of these memory semantics are configured and used. Further we will dig into the internals of how PostgreSQL implements them accompanied with demos, tool usage and preview of work in progress.
