To run a system optimally, it is important to ensure you are running the most up-to-date version of PostgreSQL. Below are some of the top reasons why you should upgrade your PostgreSQL database:
Access to new features
Keep up to date with patches
In order to receive continuous community support, it is critical for your system to be running on a supported version. Each major version of PostgreSQL is supported by the community for 5 years, until it reaches EOL.
Upgrades can be a tricky business, so careful planning and testing is required to ensure a smooth, low-downtime upgrade between PostgreSQL major versions.
How can you Upgrade PostgreSQL with Zero Downtime?
When upgrading your PostgreSQL databases, there are a number of options available.
Using PostgreSQL built-in tools, such as pg_upgrade, can involve significant downtime.
Performing a PostgreSQL Upgrade for large or high volume databases using tools such as logical replication can minimize downtime to almost zero. 2ndQuadrant engineers developed the code for logical replication, which forms the basis of the popular PostgreSQL extension, pglogical.
Our experts use first-hand knowledge of the code-base to help upgrade your current PostgreSQL database with almost zero downtime.
Our Customers’ Experiences
The Alfred Wegener Institute (AWI) is an internationally recognized institute known for expertise in polar and marine research. AWI operates on a variety of research stations which constantly collect an enormous amount of data.
As the demand presented itself, AWI invested in various PostgreSQL versions and operating systems for their applications. This decision inevitably led to a complex database infrastructure where a mixture of different PostgreSQL and OS versions were rarely working in sync.
