Aye sir. It works.
There's not much details into the documentation but the real point is
that the execute command of the PLPg/SQL actually says the DB to delay
the query planning process as late as possible,
I have also managed to build search functions at runtime using the execute
command with a dynamically built text variable.
Complex, error prone but really fast.
