Coerce 'unknown' type parameters to the right type in the fixed-params

EXECUTE ... USING 'stringconstant'.
The coercion with a CoerceViaIO node. The result is similar to the coercion
via input function performed for unknown constants in coerce_type(),
except that this happens at runtime.
Unfortunately, this entirely fails to enforce the rule that an unknown
Param be coerced the same way everywhere. You'd need a cleanup pass as
well, cf check_variable_parameters().
Yeah, you're right. I'll find a way to do the cleanup pass in fixed
params case too.
