postgres function for the query tree based normalization?

Hello,

see
http://postgresql.1045698.n5.nabble.com/pg-stat-statements-with-query-tr
ee-based-normalization-td4989745.html

Is there a plan to make this query normalization available as a
postgres function.

i.e.: select pg_norm_query (query text , OUT normed_query text )

best reagards,
