reparsing query

Hi
I knock once again with this : reparse query to XML ( last knock 5-6 years
before) .
Motivation: more info for front-end developers about query. Users of jdbc
driver
are not able to gather information from meta data about such simple query :
"select x.a,y.b from xxx x, yyy y"
Solution : modification backend/utils/adt/ruleutils.c

I've done it few years ago, but with every new version of potgresql there
is a need to modify library.
I prepared version for 9.4.1, standalone, which could be used as library
loaded by backend. I wish to have such functionality in main distro.
Is anyone interested ?
