- pgEdge Distributed Postgres extends standard Postgres for global, distributed, and multi-master deployments.
- The exec_node() function simplifies remote SQL execution across pgEdge nodes, eliminating manual logins and scripts.
- Common use cases include executing DDL statements, administrative tasks, and Spock-specific commands that don't replicate.
- exec_node() allows targeting specific nodes or all nodes, improving automation and operational safety.
- Examples include running VACUUM ANALYZE on a single node or altering system parameters cluster-wide.
- Best practices include logging executions, validating SQL, and testing in non-production environments.
- The function supports targeted DDL deployment and Spock cluster management functions.
- exec_node() integrates seamlessly into automation scripts, reducing human error and centralizing command execution.
