PostgreSQL Training


PostgreSQL Fundamentals

About

PostgreSQL (or Postgres for short) is an open source relational database management systems (RDBMS). In nearly all cases the main application interface to an RDBMS is SQL, the standardized language for accessing relational databases. Beyond SQL every RDBMS needs additional tools to handle the installation process as well as maintenance and optimization tasks. As such tasks act closely to the implementation of each RDBMS, they greatly differ from RDBMS to RDBMS - unlike SQL. The purpose of This course is an introduction to the PostgreSQL specific aspects: its architecture, installing procedure, maintenance and optimization tasks. Thus it is primarily aimed to database administrators. But it is only a starting point in these objectives and many topics are omitted. For a complete treatment we recommend to get through professional training courses offered by many consulting companies. And don't forget: there is a great and complete documentation of all the stuff we try to explain in the Wikibook on hand. Additionally some special topics are summarized in the PostgreSQL wiki. The SQL interface is out of the scope of the Wikibook on hand. If you are interested in this specific topic, you may want to refer to the Wikibook SQL, which describes the SQL standard independent from any RDBMS implementation. It's a good starting point for PostgreSQL as its implementation of SQL is very close to the standard. The Wikibook on hand is based on PostgreSQL version 10.

Mastering PostgreSQL 10

About

PostgreSQL is a Free and open-source relational database management system, It is a relational database management system. PostgreSQL is mainly influenced by Ingres.

PostgreSQL manages concurrency through multi-version concurrency control (MVCC), which gives each transaction a "snapshot" of the database, allowing changes to be made without affecting other transactions. This largely eliminates the need for reading locks and ensures the database maintains ACID principles. PostgreSQL offers three levels of transaction isolation: Read Committed, Repeatable Read, and Serializable. Because PostgreSQL is immune to dirty reads, requesting a Read Uncommitted transaction isolation level provides read committed instead. PostgreSQL supports full serializability via the serializable snapshot isolation (SSI) method.

PostgreSQL includes built-in binary replication based on shipping the changes (write-ahead logs (WAL)) to replica nodes asynchronously, with the ability to run read-only queries against these replicated nodes. This allows splitting read traffic among multiple nodes efficiently. Earlier replication software that allowed similar read scaling normally relied on adding replication triggers to the master, increasing load.

PostgreSQL includes built-in synchronous replication that ensures that, for each write transaction, the master waits until at least one replica node has written the data to its transaction log. Unlike other database systems, the durability of a transaction (whether it is asynchronous or synchronous) can be specified per-database, per-user, per-session, or even per-transaction. This can be useful for workloads that do not require such guarantees and may not be wanted for all data as it slows down performance due to the requirement of the confirmation of the transaction reaching the synchronous standby.
