PGLOGICAL
Selective logical replication for PostgreSQL
PostgreSQL
ABOUT
Physical streaming replication copies the whole cluster and cannot skip versions or filter tables. pglogical publishes logical changes so you can replicate a subset of tables (or rows) between Postgres versions, feed a read replica for RAG queries, or run online major-version upgrades without dumping the entire database.
INTEGRATION GUIDE
1. Replicate selected feature-store tables to an analytics Postgres replica
2. Online major-version upgrade of a production Postgres used by agents
3. Filter rows at the publisher so staging only receives a tenant subset
4. Keep a reporting cluster in sync without trigger-based Slony overhead
