Release 11.7.2

Release Date: 2020-04-16

  • VMware Postgres 11.7 updates the PostgreSQL database version to 11.7. Version 11.7 fixes an important security issue:

    • CVE-2020-1720: ALTER … DEPENDS ON EXTENSION is missing authorization checks.
  • PostgreSQL 11.7 includes numerous bug fixes and improvements, as highlighted in [https://www.postgresql.org/about/news/2011/). See E.1.2. Changes in the PostgreSQL 11.7 Release Notes for a complete list of changes.

  • VMware Postgres 11.7 now includes the PL/Java and PL/R procedural language extensions for Postgres. These extensions are packaged in a separately versioned download file. See Installing or Upgrading VMware Postgres for steps to download and install the extensions.

  • VMware Postgres 11.7 includes updated versions of pgBackRest, Patroni, and pgjdbc.

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

Known Issues and Limitations

  • 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.
