Verifying TDE is enabled
========================

You can find out whether TDE is present on a server by querying the
``data_encryption_version`` column of the ``pg_control_init`` table.

A value of 0 means TDE isn’t enabled. Any nonzero value reflects the
version of TDE in use. Currently, when TDE is enabled, this value is 1.

.. code:: sql

   select data_encryption_version from pg_control_init();
   __OUTPUT__
    data_encryption_version
   - ------------------------
                          1
