Impact of open_pg_tde on database operations

This page summarizes how open_pg_tde interacts with core PostgreSQL operations.

Area	Affected	Notes / Actions
Backups	Yes	Encrypted backups require open_pg_tde-aware tools. See Backup with WAL encryption.
Restore	Yes	Restored data remains encrypted; open_pg_tde transparently handles decryption. See Restore encrypted backups.
Streaming replication	Partial	Replicas must load the open_pg_tde shared library (shared_preload_libraries = ‘open_pg_tde’). Without it, the replica will fail on operations involving tde_heap.
Logical replication	No	Not affected.
Monitoring and statistics	No	Not affected, including pg_stat_statements.
Performance	Partial	Minor CPU overhead due to enabling encryption, most noticeable on random write workloads.
