What are the different replication methods in PostgreSQL?

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

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 options, enabling you to replicate specific tables or even subsets of data. It uses a publish-subscribe model, which is different from the physical replication method.

Which method is best for high availability?

For high availability, streaming replication is often preferred due to its real-time capabilities and automatic failover options. However, the best choice depends on your specific use case and requirements.
