postgres function for the query tree based normalization?

Hello,

see

http://postgresql.1045698.n5.nabble.com/pg-stat-statements-with-query-tree-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,
