The raw materials exist to do this: if you know which elements of a
query will be replaced by plpgsql variables, you can duplicate the
results via
PREPARE foo(...) AS ...
EXPLAIN EXECUTE foo(...)
Certainly there is a lot more that we can and must do about making
it easier to debug and tune plpgsql functions. But you can fix 'em
with a little determination even now...
