Oh, interesting. So this is really a datatype mismatch problem.
I'd wondered idly why you were getting the explicit casts to text
in these conditions, but now it seems that that's key to the
problem: the casts prevent these clauses from being matched to
the index. What are the declared data types of product_code
and balance_type? And of the parameters they're compared to?
