What are the different replication options available in PostgreSQL?

PostgreSQL offers several replication options, including streaming replication, logical replication, and physical replication. Would you like to know more about a specific type?

Can you explain streaming replication?

Streaming replication allows for real-time data replication from a primary server to one or more standby servers. It uses a continuous stream of WAL (Write Ahead Log) files to keep the standby servers updated.

What about logical replication?

Logical replication allows for more flexible replication setups, enabling you to replicate specific tables or databases. It uses a publish-subscribe model, which can be useful for selective data sharing.

Are there any performance considerations I should be aware of?

Yes, performance can vary based on the replication method. Streaming replication is generally more efficient for high availability, while logical replication may introduce some overhead due to its flexibility.
