Answer
Logical replication sends row-level changes to subscribers and supports selective table replication.
Quick Answer
Logical replication replicates data changes at the row level using logical decoding of the WAL. Subscribers receive INSERT, UPDATE, DELETE events for specific tables. Supports: replicating to different PostgreSQL versions, selective table replication, cross-version upgrades, and CDC (Change Data Capture) for downstream systems. More flexible than physical replication but can't replicate DDL automatically.
