PostgreSQL’s pg_stat_statements provides the basic statistics, which is sometimes not enough. 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. In this case, a user would need to calculate the aggregates, which is quite an expensive operation.",

- * pg_stat_monitor uses the hash structure to store all query statistics

- * Enabling USE_DYNAMIC_HASH uses the dshash for storing the query statistics
- * that get created in the DSA area and can grow to any size.
- *
- * The only issue with using the dshash is that the newly created hash entries
- * are explicitly locked by dshash, and its caller is required to release the lock.
- * That works well as long as we do not want to swallow the errors thrown from
- * dshash function. Since the lightweight locks acquired internally by dshash
- * automatically get released by error.
- * But throwing an error from pg_stat_monitor would mean erroring out the user query,
- * which is not acceptable for any stat collector extension.
- *
- * Moreover, some of the pg_stat_monitor functions perform the sequence scan on the
- * hash table, while the sequence scan support for dshash table is only available
- * for PG 15 and onwards.
- * So until we figure out the way to release the locks acquired internally by dshash
- * in case of an error while ignoring the error at the same time, we will keep using
- * the classic shared memory hash table.
