Delegate operand normalization to df.if() and remove the duplicated PL/pgSQL helper from fresh installs. Update the 0.2.5-to-0.2.6 migration to replace the operator helpers before dropping df.ensure_durofut with RESTRICT. Preserve binary-only upgrade compatibility and support partial expressions created before ALTER EXTENSION.
