See Installing or Upgrading VMware Postgres for information about the RPM package contents and upgrade instructions.

Known Issues and Limitations

  • 884 - pg_auto_failover does not support extra table spaces.
  • VMware does not support using the repmgr witness server, as it is not a full and complete solution for detecting split brain scenarios. Use external utilities (not provided by VMware) to prevent a split brain situation and to initiate fail-overs using the repmgr utilities.
  • VMware does not support using the deprecated XML2 module.
  • You cannot install VMware Postgres alongside an existing Red Hat Enterprise Linux PostgreSQL installation.
  • All software components in this release, including the client ODBC and JDBC drivers, are supported only on Red Hat Enterprise Linux (RHEL) version 7 and CentOS 7 systems.
