Impact of pg_tde on database operations

This page summarizes how pg_tde interacts with core PostgreSQL operations.

Area	Affected	Notes / Actions
Backups	✅ Yes	Encrypted backups require pg_tde-aware tools. See Backup with WAL encryption.
Restore	✅ Yes	Restored data remains encrypted; pg_tde transparently handles decryption. See Restore encrypted backups.
Streaming replication	⚠️ Partial	Replication requires pg_tde on replicas. If keys are local, they must be manually copied; shared KMS works automatically.
Logical replication	?	?
Monitoring and statistics	?	how will pg_stat_monitor be affected?
Extensions	?	?
Maintenance operations	?	?
Upgrades and migrations	?	?
Performance	⚠️ Slight	Minor CPU overhead due to enabling encryption.
Configuration management	✅ Yes	pg_tde.conf parameters affect key handling and WAL encryption.
