FOR PORTION OF valid_at FROM $1 TO $2 fails with "could not determine data type of parameter $1", so using PREPARE requires users to say $1::date etc. But transformForPortionOfClause() already coerces the bounds, since it builds a constructor for the targeted range. We just need to store the coerced expressions in targetFrom and targetTo. This also improves pg_get_ruledef(), which now renders an untyped NULL bound as NULL::date instead of NULL::unknown.
