Introduction
This chapter basically deals with the server architecture and server control. Initially, we will discuss the different options available to start and stop the PostgreSQL server. As an administrator, one should be aware of the different methods available in order to use the appropriate option in emergency situations or during maintenance operations. We then move onto discussing different server parameters and the tuning aspects related to them. Some important server parameters that help improve the overall server throughput and performance are discussed here from an optimization perspective.
