For full-cluster Transparent Data Encryption (TDE), the current plan is
to encrypt all heap and index files, WAL, and all pgsql_tmp (work_mem
overflow). The plan is:
https://wiki.postgresql.org/wiki/Transparent_Data_Encryption#TODO_for_Full-Cluster_Encryption
We don't see much value to encrypting vm, fsm, pg_xact, pg_multixact, or
other files. Is that correct? Do any other PGDATA files contain user
data?
