May 8, 2025 PostgreSQL 17.5, 16.9, 15.13, 14.18, and 13.21 Released! Web servers serving static web pages can be combined quite easily by merely load-balancing web requests to multiple machines. In fact, read-only database servers can be combined relatively easily too. Unfortunately, most database servers have a readwrite mix of requests

Postgres-XL is a shared nothing, multi-master clustering solution which can transparently distribute a table on a set of nodes and execute queries in parallel of those nodes. It has a additional component called Global Transaction Manager GTM for providing globally consistent view of the cluster. The project is based on the latest available 9

Shared Data Shared storage allows multiple nodes to access the same data. This can simplify data consistency and reduce the need for complex replication mechanisms. PostgreSQL Node.js How

The first constraint that is needed is for the colocation of the VIPs pgdbrepvip, pgdbclivip and the PostgreSQL service, for the node that is running as Master. This is so that the pgdbrepvip and pgdbclivip are always started on the same node that is running the postgresql resource in Master mode.

A PostgreSQL multi-master replication system can do this. So the multi-master replication adds an element of bi-directionality to the process. PostgreSQL Multi-master replication lets multiple nodes accept write queries and all of the nodes involved contain the same data. The main purpose of multi-master replication, of course, is high

Is there a way we can setup multinode cluster in Postgres like Oracle RAC Oracle RAC allows multiple computers to run Oracle RDBMS software simultaneously while accessing a single database, thus Multi Node Cluster in Postgres. Ask Question Asked 5 years, 5 months ago. Modified 5 years,

Learn how to set up a high-availability 3-node PostgreSQL cluster with Patroni on Ubuntu 24.04, ensuring your database is always online and resilient to failures. Discover how Patroni and HAProxy work together to provide seamless load balancing, failover, and performance optimization.

PostgreSQL offers built-in streaming replication beginning in version 9. Many PostgreSQL HA solutions use the built-in streaming replication to provide the mechanism for multiple PostgreSQL replica nodes to be kept in sync with the primary. Several of these options are discussed in the PostgreSQL HA architectures section later in this document.

Multi-Master Asynchronous Replication Involves multiple standalone PostgreSQL instances with asynchronous replication and conflict resolution mechanisms. Multi-Master Sharded PostgreSQL with a Coordinator Data is sharded across multiple standalone PostgreSQL instances. A coordinator node handles application connections and directs requests to

PostgreSQL Multi-node Quorum-based, Zero Data Loss, and HA Failover, Switchover Solution digoal April 28, 2021 12,178 0. In this article, we discuss the implementation of a quorum-based PostgreSQL cluster with multiple nodes with zero data loss and high availability architecture.
