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 andconfiguration. 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

PostgreSQL High Availability Cookbook. Managing a reliable PostgreSQL database - Second Edition
Shaun Thomas
Databases are nothing without the data they store. In the event of a failure - catastrophic or otherwise - immediate recovery is essential. By carefully combining multiple servers, it’s even possible to hide the fact a failure occurred at all.From hardware selection to software stacks and horizontal scalability, this book will help you build a versatile PostgreSQL cluster that will survive crashes, resist data corruption, and grow smoothly with customer demand. It all begins with hardware selection for the skeleton of an efficient PostgreSQL database cluster. Then it’s on to preventing downtime as well as troubleshooting some real life problems that administrators commonly face. Next, we add database monitoring to the stack, using collectd, Nagios, and Graphite. And no stack is complete without replication using multiple internal and external tools, including the newly released pglogical extension. Pacemaker or Raft consensus tools are the final piece to grant the cluster the ability to heal itself. We even round off by tackling the complex problem of data scalability.This book exploits many new features introduced in PostgreSQL 9.6 to make the database more efficient and adaptive, and most importantly, keep it running.

PostgreSQL. Kurs video. Zostań administratorem systemów IT
Piotr Tenyszyn
Obierz kurs na... zarządzanie relacyjnymi bazami danych Jeśli planujesz karierę administratora systemów IT, temat zarządzania bazami danych powinien - a nawet więcej: musi - być Ci bliski. Bazami danych można zarządzać na rozmaite sposoby, jednym z nich jest model relacyjny. Jeśli masz lub będziesz mieć do czynienia z tego typu bazą danych, prędzej czy później zetkniesz się z PostgreSQL, alternatywnie nazywanym Postgres. Jest to jeden z trzech - obok MySQL i SQLite - najpopularniejszych otwartych systemów zarządzania relacyjnymi bazami danych. Dodatkowo to jeden z niewielu systemów zarządzania bazami danych, które oferują podejście obiektowo-relacyjne. Postgres (lub PostgreSQL) wywodzi się z projektu Ingres prowadzonego na Uniwersytecie Kalifornijskim. Wskutek wieloletnich przekształceń i udoskonaleń powstał system, którego używa się dziś. Charakteryzuje go hybrydowość - podejście obiektowo-relacyjne to prawdziwy rarytas wśród systemów zarządzania bazami danych. Jest to oprogramowanie otwarte, co pozwala korzystać z niego bez żadnych opłat, ale też modyfikować kod źródłowy w zależności od własnych potrzeb. Ponieważ twórcy i użytkownicy PostgreSQL pracują nad nim nieustannie od ponad dwudziestu lat, system stał się niezawodny i wszechstronny. Zdecydowanie warto go poznać! Co Cię czeka podczas naszego profesjonalnego szkolenia Dzięki naszemu wyjątkowemu kursowi: Dowiesz się, czym jest PostgreSQL Nauczysz się konfigurować w nim swoje środowisko pracy Poznasz zasady pracy z bazą danych Postgres Stworzysz bazę, tabelę i będziesz pisać do nich zapytania Uaktywnisz użytkowników i nadasz im odpowiednie uprawnienia Skonfigurujesz PostgreSQL w Google Cloud Co więcej... W trakcie szkolenia poznasz podstawowe zagadnienia związane z systemem Postgres, dzięki czemu będziesz w stanie samodzielnie kontynuować jego poznawanie PostgreSQL. Kurs video. Zostań administratorem systemów IT zakończysz na poziomie podstawowym - dającym Ci podstawowe informacje o środowisku PostgreSQL i jego najważniejszych funkcjach. Odbywszy szkolenie, będziesz w stanie stworzyć własną bazę danych i nią zarządzać. Obiektowo-relacyjne bazy danych Obiektowo-relacyjna baza danych stanowi połączenie relacyjnej bazy danych z bazą typu obiektowego. W systemie PostgreSQL (podobnie zresztą jak w MySQL) dane są utrzymywane w postaci tabel opisanych odpowiednimi relacjami. Manipulacja tymi danymi odbywa się z użyciem języka zapytań. System integruje podejście relacyjne z podejściem obiektowym, poszerzając narzędzia znane z relacyjnych baz danych o narzędzia obiektowe, takie jak obiekty, klasy i dziedziczenie. W porównaniu z obiektową bazą danych baza mieszana jest „bogatsza” o strukturalny język zapytań, którego w podejściu obiektowym nie znajdziemy.

Learn how to work with PostgreSQL as if you spent the last decade working on it. PostgreSQL is capable of providing you with all of the options that you have in your favourite development language and then extending that right on to the database server. With this knowledge in hand, you will be able to respond to the current demand for advanced PostgreSQL skills in a lucrative and booming market.PostgreSQL Server Programming will show you that PostgreSQL is so much more than a database server. In fact, it could even be seen as an application development framework, with the added bonuses of transaction support, massive data storage, journaling, recovery and a host of other features that the PostgreSQL engine provides. This book will take you from learning the basic parts of a PostgreSQL function, then writing them in languages other than the built-in PL/PgSQL. You will see how to create libraries of useful code, group them into even more useful components, and distribute them to the community. You will see how to extract data from a multitude of foreign data sources, and then extend PostgreSQL to do it natively. And you can do all of this in a nifty debugging interface that will allow you to do it efficiently and with reliability.
