The pgpro_stats extension provides a means for tracking planning and execution statistics of all SQL statements executed by a server. In addition to tracking local statements, the pgpro_stats extension collects the aggregated statistics for distributed queries that involve multiple nodes in a cluster. This allows users to get a better understanding of how system resources are being used for distributed queries.

The architecture of Shardman additions to thepgpro_stats extension is described in Section 7.8.
