EDB adds quorum commit to distributed Postgres 6.4

EDB has released version 6.4 of its Postgres Distributed (PGD) solution, which includes enhancements such as quorum commit, native connection pooling, and support for PostgreSQL large objects. The quorum commit feature ensures a unified transaction outcome across cluster nodes before finalizing a transaction, addressing potential risks from conflicting writes in distributed systems. This update targets organizations in sectors like banking, payments, telecommunications, and infrastructure, aiming to provide the same consistency guarantees previously reliant on proprietary databases. The Connection Manager now includes native connection pooling, reducing the need for external connection poolers and streamlining operations by integrating with PGD's Raft consensus layer. This integration allows for automatic route adjustments during failover and improved monitoring capabilities. Additionally, the update expands replication support to include PostgreSQL large objects, enhancing the applicability of distributed Postgres for managing mixed data sets in sectors like government, healthcare, and financial services. EDB also noted a Gartner forecast that by 2030, over 75% of enterprises in Europe and the Middle East will have repatriated workloads to their home jurisdictions, emphasizing the importance of consistent data management across locations. EDB aims to strengthen Postgres's position in the market by focusing on transaction integrity in distributed environments while minimizing reliance on additional infrastructure components.

Postgres and Data Sovereignty Address Datacenter Energy Crisis

Lizzy Nguyen from EDB discusses the relationship between Postgres, data sovereignty, and energy constraints in datacenters. Local opposition to hyperscale datacenter constructions in the US is growing, highlighting energy consumption and regulatory challenges. AI-driven datacenters currently account for about 1.5% of global electricity consumption, projected to rise to nearly 3% by 2030 according to the International Energy Agency (IEA). Datacenter expenditures are expected to grow through 2029, with significant complexities in constructing necessary infrastructure for the first billion AI agents, which may take up to seven years. Data sovereignty and localized deployments are emerging as strategic responses to energy constraints, impacting deployment architecture and cost models for operators.

AI and data sovereignty in Postgres: An answer to the datacenter energy crisis

This year has seen significant developments in datacenter expansion across various regions, including Arkansas, Southern California, Nevada, Pennsylvania, West Virginia, and Box Elder, Utah, with localities concerned about energy consumption and infrastructure demands. In the UK, OpenAI's "Stargate UK" initiative has faced challenges due to energy consumption and regulatory scrutiny. New hyperscale datacenters often face grid-connection delays of up to seven years, and global spending on datacenters could reach one trillion by 2030. AI-driven datacenters currently account for about 1.5% of global electricity consumption, projected to rise to nearly 3% by 2030. The urgency for additional datacenters near energy sources is increasing, with IDC forecasting one billion agents executing 217 billion daily actions by 2029. 95% of global enterprises plan to develop their own AI and data platforms within the next 780 days. The BFSI sector typically allocates 6-12% of revenue to IT spending, compared to 3-5% in other industries. Only 13% of enterprises leveraging AI focus on control, efficiency, and sustainability in their data strategies. Leading BFSI organizations are committing to carbon neutrality and developing sovereign AI and data platforms. EDB Postgres AI aims to enhance energy efficiency in datacenters, potentially reducing energy consumption by up to 81% and emissions by 87%. Organizations adopting this model can achieve a fivefold return on investment and improved operational control.

EDB Releases PGD 6.4 with Quorum Commit, Bringing True Distributed Consistency to Mission-Critical Postgres

EnterpriseDB (EDB) has released EDB Postgres Distributed (PGD) 6.4, featuring three key enhancements: Quorum Commit for cross-node consistency, integrated connection pooling via the native Connection Manager, and full replication support for PostgreSQL large objects. Quorum Commit ensures that all nodes in a cluster reach consensus before committing transactions, addressing issues with traditional replication. The integrated Connection Manager simplifies operations by eliminating the need for external pooling solutions and providing cluster-aware routing and automatic failover. The support for large objects allows for the management of diverse data types within a single database environment. PGD 6.4 is available as a stand-alone distribution and will be integrated into EDB Postgres AI in June.

Graph Queries Across Billions of Rows of Scattered Data with Postgres and Apache AGE™

Postgres engines can now connect to large data repositories using extensions like pg_lake, allowing access to files in object storage formats such as CSV, JSON, Apache Parquet™, and Apache Iceberg™. The Apache AGE™ extension enhances data usability through graph relationships, enabling complex queries that require both graph traversal and analytical aggregation. Apache AGE introduces openCypher graph query support within Postgres, allowing for integration without data movement, as both Iceberg tables and graphs reside in the same database. This integration facilitates the construction of graphs from lake tables, allows for combining SQL and Cypher queries, and simplifies operational processes by consolidating application connection, security, and backups into a single workflow. An example of this integration is a healthcare platform using Iceberg tables on Amazon S3, which includes various data types such as claims, providers, patients, and referrals. To utilize these features, necessary Postgres extensions must be loaded, with pg_lake operating alongside a sidecar, the pgduck_server, for Iceberg operations.

CVE-2024-55638: Highly Critical Drupal Core Vulnerability Threatens PostgreSQL Sites with Remote Code Execution (RCE)

A critical vulnerability, CVE-2024-55638, has been identified in Drupal Core, affecting installations using PostgreSQL as their backend database. This vulnerability involves PHP Object Injection, which can lead to full Remote Code Execution (RCE) when combined with another deserialization flaw. It cannot be exploited independently but increases the risk for Drupal installations that use third-party modules or custom code that improperly employs the unserialize() function. The affected versions include Drupal Core 7.x prior to 7.102, 8.0.0 and above prior to 10.2.11, and 10.3.0 prior to 10.3.9, with patched versions being 7.102, 10.2.11, and 10.3.9. The vulnerability is particularly relevant for sites using PostgreSQL, and organizations are urged to upgrade to the patched versions and audit their code for unsafe unserialize() usage. Currently, there are no confirmed reports of exploitation in the wild, but the risk remains high due to insecure deserialization bugs in third-party modules. The EPSS score for this vulnerability is 9.93%, indicating a significant likelihood of exploitation in the near future.
