Overview of this book

PostgreSQL database servers have a common set of problems that they encounter as their usage gets heavier and requirements get more demanding. Peek into the future of your PostgreSQL 10 database's problems today. Know the warning signs to look for and how to avoid the most common issues before they even happen. Surprisingly, most PostgreSQL database applications evolve in the same way—choose the right hardware, tune the operating system and server memory use, optimize queries against the database and CPUs with the right indexes, and monitor every layer, from hardware to queries, using tools from inside and outside PostgreSQL. Also, using monitoring insight, PostgreSQL database applications continuously rework the design and configuration. On reaching the limits of a single server, they break things up; connection pooling, caching, partitioning, replication, and parallel queries can all help handle increasing database workloads. By the end of this book, you will have all the knowledge you need to design, run, and manage your PostgreSQL solution while ensuring high performance and high availability

Using a contrib module


While some contrib programs such as pgbench, are directly executable, most are utilities that you install into a database in order to add extra features to them.

As an example, to install the module into a database named abc, the following command line would work (assuming the RedHat location of the file):

$ psql -d abc -f /usr/share/postgresql/contrib/pg_buffercache.sql 

You could instead use the pgAdmin III GUI management utility, which is bundled with the Windows installer for PostgreSQL, instead of the command line:

  1. Navigate to the database you want to install the module into.
  2. Click on the SQL icon in the toolbar to bring up the command editor.
  3. Choose File/Open. Navigate to C:\ProgramFiles\PostgreSQL/version/share/contrib/pg_buffercache.sql and open that file.
  4. Execute using either the green arrow or Query/Execute.

You can do a quick test of the module installed on any type of system by running the following quick query:

SELECT * FROM pg_buffercache;

If any results come back, the module was installed. Note that pg_buffercache will only be installable and usable by database superusers.
