Hello.
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.
