particular user/db/query. The function pg_stat_statements_reset() is extended to accept userid, dbid, and queryid as input parameters. Now, it can discard the statistics gathered so far by pg_stat_statements corresponding to the specified userid, dbid, and queryid. If no parameter is specified or all the specified parameters have default value aka 0, it will discard all statistics as per the old behavior. The new behavior is useful to get the fresh statistics for a specific user/database/query without resetting all the existing statistics.
