Even if he did, that wouldn't affect the source form of the query.
Insertion of explicit constant values and casts like that isn't
something plpgsql would do on its own either. My bet is that this has
got nothing to do with plpgsql, and in fact the query was generated
client-side using some rather ill-designed parameter substitution code.
If this can actually be reproduced in bare plpgsql, I would like to see
a complete test case.
