The major shortcoming in pg_stat_statements is that it accumulates all the queries and their statistics and does not provide aggregated statistics nor histogram information.

+#### Installing from Trunk
+
+You can install `pg_stat_monitor` from [Trunk (A PostgreSQL Extensions Registry)](https://pgt.dev/) using the [Trunk CLI](https://github.com/tembo-io/trunk?tab=readme-ov-file#installation).
+
+Use the following command:
+
+```
+trunk install pg_stat_monitor
+```
+
 ### Configuration
 
 You can find the configuration parameters of the `pg_stat_monitor` extension in the `pg_settings` view. To change the default configuration, specify new values for the desired parameters using the GUC (Grant Unified Configuration) system. To learn more, refer to the [Configuration parameters](https://docs.percona.com/pg-stat-monitor/configuration.html) section of the documentation.
