I learned about the logical and physical structures of Database cluster, the layout of the database clusters, the databases, the files associated with tables and indexes, and the tablespaces. Read about the internal layout of a heap table file, and the methods of writing and reading tuples. In chapter 2 we learn about the process and memory architectures, how the PostgreSQL server is composed by a postgres server process, that is a parent of all in a PostgreSQL server, which is called 'postmaster' in the version we are working on. The chapter 3 explains the query processing and it consists in five subsystems: parser, analyzer, rewriter, planner and executor. It also shows the process of cost estimation, creating the plan tree, and how the executor and join operations work. -- This is an automated message from the Apache Git Service.
