Master streaming replication with hot standby to enable high availability for Postgres across multiple servers. Learn about synchronous and asynchronous replication, archive-based and streaming approaches, and standby recovery workflows.
Set up streaming replication with a hot standby in postgres by installing, enabling archive mode, creating a cluster, configuring primary and standby, and validating with sample tables.
Set up PostgreSQL streaming replication between a primary and standby server, enabling log shipping, SSH key generation, passwordless access, and archiving for backup.
Demonstrates setting up replication with a standby server, promoting it to primary, and performing failback using pg rewind and log shipping for consistency.
Explore how to configure a PostgreSQL setup with one master and multiple standbys, including archiving logs, configuring replication, and validating failover ready standby nodes.
Learn how hardware configuration, RAM and disk layouts—SSD vs HDD—and tablespaces affect PostgreSQL performance, and tune query plans, indices, and parallelism using explain analyze, vacuum, and analyze to optimize execution.
Tune PostgreSQL performance by examining autovacuum and vacuum settings, analyzing and explaining query plans, and optimizing with indexes, cost parameters, and sort strategies.
Master external tables with file_fdw to read csv and excel data via foreign data wrappers; create external tables, view data read-only, and snapshot data by copying to a local table.
This lecture explains the MySQL foreign data wrapper for PostgreSQL, covering installation, server and user mapping, and creating foreign tables to access MySQL data.
Learn how PG wait sampling uses an extension to capture per process read events, history of rate events, and profiling data stored in memory hash tables and log tables.
Discover PostgreSQL 10 features, including partition by range for partitioned tables and object-based publications and subscriptions for selective replication, plus big data and scaling enhancements.

Take your career to the next level. Move into highly sought after PostgreSQL Database Administrator roles
With the increasing popularity of Open Source Databases, organisations are looking for best alternatives among the widely available choices in the market.
Among the various choices available, PostgreSQL is the most widely adopted database in recent years in the industry. Thousands of companies are using PostgreSQL for their business critical as well as non-critical applications. PostgreSQL is not just limited to one industry – it is pretty much everywhere.
But why PostgreSQL? Why not any other open source DBMS like MySQL or MariaDB?
The reason is - PostgreSQl is the most advanced open source database management system that are available today. It is - ORDBMS, that is object relation database management system.
PostgreSQL is the best tool as it is available for free and it is open. It will never be bought. Its source code is available under PostgreSQL license which is a liberal open source license. You are free to use, modify and distribute PostgreSQL in any form.
Moreover, PostgreSQL comes with many features aimed to help developers build applications. It also helps administrators to protect data integrity and build fault-tolerant environments. It is extensible. For example, you can define your own data types, build custom functions or even write code from different programming languages without recompiling your database.
Also, because of the advanced features and powerful capabilities, the adoption of PostgreSQL is increasing widely in the market since past few years. It requires very minimum maintenance efforts because of its stability. Therefore, applications based on PostgreSQL have a low total cost of ownership in comparison with other database management systems.
Just look at these numbers.
According to Bureau of Labor Statistics, employment of database administrators is projected to grow 11 percent from 2016 to 2026, faster than the average for all occupations. Growth in this occupation will be driven by the increased data needs of companies across the economy.
According to indeed company, average salary for PostgreSQL DBA is $94,611 per year.
According to Bureau of Labor Statistics , Database Administrators rank # 5 in best technology jobs

What if I don’t have any need for learning PostgreSQL course right now?
Some of the major issues in terms of databases today are availability, scalability and security.
PostgreSQL is object-relational database management system and has a lot of capability. It is built using an object-relational model and supports complex structures and a range of built-in and user-defined data types. It provides extensive data capacity.
Moreover postgreSQL is trusted for its data integrity. PostgreSQL is fully ACID that is - atomicity, consistency, isolation and durability compliant and therefore ideal for Online Transaction Processing workloads as well as for analytics.
The lack of PostgreSQL expertise is the number one challenge today. There is a shortage of PostgreSQL professionals today. Database administrators’ job is projected to grow 11 percent from 2016 to 2026, faster than the average for all occupations.
As the statistics and figures show – there is an advancement in technology is rapidly expanding into our lives each and every day, meaning even though you may not be directly using any of this right now, sooner or later you will run into it inevitably.
