Details

If you'd like to take your PostgreSQL skills further, this is the course for you. This internationally available course will cover the more advanced steps in optimising and managing your database.

This course provides an in-depth insight into advanced PostgreSQL topics such as indexing, storage parameters, optimization, replication, monitoring, etc.

It deals with the technical foundation required for replication, scaling, point-in-time recovery and the successful operation of synchronous and asynchronous replication solutions.

The details of processing are examined, which are essential for optimization and performance tuning, so you can get the most out of your system and your queries.
