I think it makes more sense to have it fail. If the user wants to retry in text mode, they can do that easily enough; but if we make it fall-back automatically and they set up the received wrongly by mistake, they would pay the performance penalty without noticing. -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
