PostgreSQL Administration Cookbook. Effective database management for administrators - Third Edition
Gabriele Bartolini, Hannu Krosing, Gianni Ciolli, Simon Riggs
PostgreSQL is a powerful opensource database management system; now recognized as the expert's choice for a wide range of applications, it has an enviable reputation for performance and stability. PostgreSQL provides an integrated feature set comprising relational database features, object-relational, text search, Geographical Info Systems, analytical tools for big data and JSON/XML document management.Starting with short and simple recipes, you will soon dive into core features, such as configuration, server control, tables, and data. You will tackle a variety of problems a database administrator usually encounters, from creating tables to managing views, from improving performance to securing your database, and from using monitoring tools to using storage engines. Recipes based on important topics such as high availability, concurrency, replication, backup and recovery, as well as diagnostics and troubleshooting are also given special importance.By the end of this book, you will have all the knowledge you need to run, manage, and maintain PostgreSQL efficiently.
PostgreSQL. Receptury dla administratora
Poznaj najlepsze przepisy na pracę z PostgreSQL! Jak zapewnić bezpieczeństwo bazom danych? Jak uruchomić kilka serwerów baz danych w ramach jednego systemu operacyjnego? Jak zarządzać użytkownikami i ich uprawnieniami? PostgreSQL to jedna z najbardziej zaawansowanych baz danych o otwartym kodzie źródłowym. Przez wiele lat była niedoścignionym wzorem dla innego darmowego rozwiązania — MySQL. Dziś znajduje zastosowanie wszędzie tam, gdzie wymagana jest najwyższa niezawodność i wydajność, a brak konieczności zapłaty gra kluczową rolę. Stosunek jakości do ceny w przypadku PostgreSQL zmierza do nieskończoności! Trzymasz w rękach książkę zawierającą liczne przepisy na najlepsze wykorzystanie PostgreSQL. System ten sprawdza się zawsze, gdy chcesz szybko i bezproblemowo osiągnąć zamierzone cele. W trakcie lektury dowiesz się, jak nawiązać połączenie z serwerem, skorzystać z graficznych lub tekstowych narzędzi administracyjnych oraz bezpiecznie zmienić hasło administratora. Ponadto nauczysz się kontrolować przestrzeń dyskową wykorzystywaną przez poszczególne bazy danych, tworzyć tabele, ładować dane oraz zarządzać użytkownikami i ich uprawnieniami. Autorzy dużo miejsca poświęcają kwestii bezpieczeństwa. W końcu dane to najcenniejsza rzecz, jaką przechowuje się w bazach! Każdy z rozdziałów przynosi ogrom wiedzy o różnym poziomie skomplikowania. Zaawansowanych użytkowników zainteresuje rozdział poświęcony replikacji, a tych początkujących rozdział traktujący o uruchamianiu i zatrzymywaniu serwera baz danych. Ta książka przyda się po prostu wszystkim użytkownikom PostgreSQL! Zalety PostgreSQL w kontekście innych rozwiązań bazodanowych Udostępnianie serwera w sieci Zastosowanie narzędzia psql do wykonywania zapytań Sprawdzanie wersji serwera Lista baz danych na serwerze Planowanie nowej bazy danych Parametry, ich znaczenie i ustawianie Uruchamianie i zatrzymywanie serwera Ponowne ładowanie plików konfiguracyjnych Przyznawanie użytkownikom własnych baz danych Wiele serwerów baz danych w ramach jednego systemu operacyjnego Generowanie danych testowych Tworzenie kont użytkowników i zarządzanie nimi oraz ich uprawnieniami Równoległe wykonywanie zadań — polecenie pg_batch Monitorowanie i diagnostyka serwera PostgreSQL Przygotowywanie kopii bezpieczeństwa Zobacz, co możesz osiągnąć razem z bazą PostgreSQL!
Kirk Roybal, Jim Mlodgenski, Hannu Krosing, PostgreSQL
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.
