    WIP: Add support for copying node tree into single allocation.
    
    As an example as to why one would want that, here's a
    MemoryContextStats for the same query being added to the
    plancache. The query is just a randomly selected one among the queries
    issued by \d+.
    
    PREPARE foo AS SELECT c.relchecks, c.relkind, c.relhasindex, c.relhasrules, c.relhastriggers, c.relrowsecurity, c.relforcerowsecurity, false AS relhasoids>
    EXECUTE foo ;
