+ This chapter gives an overview of the internal structure of the
+ backend of <span class="productname">PostgreSQL</span>. After having
+ read the following sections you should have an idea of how a query
+ is processed. This chapter is intended to help the reader
+ understand the general sequence of operations that occur within the
+ backend from the point at which a query is received, to the point
+ at which the results are returned to the client.
