Features and Changes
-
The JDBC driver for Tanzu Postgres is now available for Tanzu Postgres 15. Java programs can use the driver to connect to a PostgreSQL database using standard database-independent Java code.
For Red Hat Enterprise Linux (RHEL) versions 8 and 9, version 42.7.3 of the JDBC driver is now supported for VMware Postgres 12–16. For RHEL version 7, version 42.6.0 is supported.
- This release introduces the extension h3-pg, which adds PostgreSQL bindings for H3.
- This release introduces the extension pg_cron, a job scheduler.
- This release introduces the extension pg_stat_monitor for monitoring query performance.
- This release introduces the extension pg_failover_slots, which allows you to use logical replication slots across a physical failover in a physical streaming replication architecture.
- For Debian, this release adds a post-installation step that creates a default user account with permissions for the default database.
- This release introduces the advanced_password_check extension for checking passwords against password policies.
Release 15.6.0
Release Date: February 15, 2024
This topic describes the changes in VMware Postgres v15.6.0.
Supported Platforms
VMware Postgres is supported on Red Hat Enterprise Linux (RHEL) version 7, CentOS 7, RHEL version 8, RHEL version 9, and Ubuntu 22.04. This applies both to the core database software, as well as client components such as ODBC and JDBC.
Each RPM file included with VMware Postgres automatically installs additional operating-system package dependencies as needed. However, no Extra Packages for Enterprise Linux (EPEL) repository packages are required for VMware Postgres.
Network connectivity is required between all PostgreSQL hosts and clients.
ODBC support requires either the UnixODBC or iODBC driver manager on each client machine.
JDBC support requires Java 8 or higher on each client machine.
IMPORTANT: For Red Hat Enterprise Linux 64-bit 8.x (RHEL8) deployments:
- Customers upgrading from RHEL7 to RHEL8 need to reindex all non-numeric indexes due to a change in glibc.
- RHEL8 supports Python 3. Existing PL/Python customers who upgrade from RHEL7 to RHEL8 need to verify all their existing Python functions with Python 3.

Upgrading to VMware Postgres 15.x
For upgrade details, see Upgrading VMware Postgres.
PostGIS customers on Postgres versions 10, 11, or 12 can only upgrade to Postgres 15.x after they upgrade their existing Postgres to the latest minor version, and then upgrade PostGIS version to 3.X.
Known Issues and Limitations
- 773 - In an HA configuration, a failover scenario overwrites the files that reside in the data directory. Therefore keep important read-only files outside the configured data directory. Common read-only files include SSL certificates, keys, or different configuration files for primary and mirrors.
Deprecated Features
- The xml2 extension is included in VMware Postgres, but it is deprecated and unsupported.
