Known Issues and Limitations

  • 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.
