Transparent Data Encryption
===========================

Transparent data encryption (TDE) is an optional feature supported by
EDB Postgres Advanced Server and EDB Postgres Extended Server from
version 15.

It encrypts any user data stored in the database system. This encryption
is transparent to the user. User data includes the actual data stored in
tables and other objects as well as system catalog data such as the
names of objects.
