Yeah. I suggest never changing subject lines, because Gmail has the nasty (mis-)feature of making such a response into a completely new thread. I don't know if Google paid mail service behaves in the same way. So if you change Subject, please do include a URL to the previous thread if necessary, for the benefit of people reading on Gmail. I wouldn't worry about this for any other individual email provider, but Gmail is by far the largest fraction of subscribers :-( I guess this shows just how much better Google made webmail systems than what existed at the time. -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
