Обсуждение: Regarding pg_stat_statements
Hi,
As we know that "pg_stat_statements" will monitor the queries after normalizing the queries(Removes the values present in query). I want to know is there a way to store those normalized values because I want to check the type of data(values) ,range of data that is being hit to the database. I am using Postgres 9.4

You may be interested in the pg_qualstats extension: https://github.com/dalibo/pg_qualstats The purpose of the extension is to track values like pg_stat_statements, but at the predicate level rather than statement level. It stores normalized predicates as well as constants. The documentation is here: http://powa.readthedocs.org/en/latest/stats_extensions/pg_qualstats.html#pg-qualstats It won't give you all normalized values though, only those present in predicates. -- Ronan Dunklau http://dalibo.com - http://dalibo.org

I am using Postgres 9.4 BTW, this really isn't appropriate for the pgsql-hackers list; please ask your next question like this on pgsql-general or pgsql-performance. However, pg_qualstats is what you want: http://powa.readthedocs.org/en/latest/stats_extensions/pg_qualstats.html -- Josh Berkus PostgreSQL Experts Inc. http://pgexperts.com
