Viewing Parse Tree of a query from front end

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

I know this sounds kind of silly, but I think I would like to be able to
send a query to PostgreSQL, and have it parse it into a tree, and then pass
the tree back to me somehow. Of course, I don't want the query to actually
execute.

Writing the front end application of materialized views, I would like to see
if I can deduce what triggers to put where based on the parse tree a query
returns.

Are there any tools to do this? Is this something that exists but is not
documented? Perhaps we can add a "PARSE TREE <query>" command?
