EnterpriseDB (EDB), a leading sovereign AI and data company, announced EDB Postgres Distributed (PGD) 6.4, the distributed transactional foundation of EDB Postgres AI—introducing three landmark capabilities: Quorum Commit for true cross-node distributed consistency, integrated connection pooling through the native Connection Manager, and full support for PostgreSQL large objects.
Together, these capabilities deliver the durability guarantees and architectural simplicity that Tier 1 financial and infrastructure applications demand, according to EDB.
The most consequential addition in PGD 6.4 is Quorum Commit; a pre-commit coordination mechanism that enforces a single, coherent global truth across every node in the cluster before any transaction is locally committed. Unlike traditional synchronous replication, which confirms only that a replica has received a record, Quorum Commit coordinates the content of concurrent writes across data centers in real time, the company said.
"Postgres has become the de facto standard for modern applications. Yet until now, organizations running high-value workloads in banking, payments, or telecom were forced to fall back on legacy enterprise RDBMS for their strongest consistency requirements. PGD 6.4 changes that, delivering the same distributed consistency those systems were built on, now fully Postgres native," said Jozef de Vries, SVP, database engineering at EDB.
PGD 6.4 extends the built-in Connection Manager introduced in PGD 6.0 with native connection pooling, eliminating the need for external poolers such as pgBouncer in most production topologies. Because the Connection Manager is integrated directly with PGD's Raft consensus layer, it provides capabilities no external proxy can match: cluster-aware routing at both the cluster and region levels, automatic failover routing that responds to consensus changes in real time, and unified observability through PostgreSQL's own logging and monitoring views, the company said.
PGD 6.4 adds full replication support for PostgreSQL large objects—binary data structures that were previously unavailable in distributed Postgres environments. This brings a class of workloads into the PGD fold that were previously excluded: applications managing scanned documents, image archives, binary payloads, or mixed transactional and unstructured data within a single database. Financial institutions, government agencies, and healthcare operators commonly maintain exactly these hybrid schemas alongside their core transactional tables.
PGD 6.4 is now available as a stand-alone distribution and will be available as part of EDB Postgres AI in June.
