Undoubtedly they are from plpgsql variable substitution.  As a general
rule, variables in a plpgsql function should never be named the same as
any table or field name that you need to access in that function,
because plpgsql isn't smart enough to tell whether it ought to
substitute its variable for a reference or not.  It will always do so,
even in cases where there arguably might be a way for it to tell that
it shouldn't (and there are cases where it simply couldn't tell, anyway).
