You should configure your MUA to send plaintext too and not only html, as some
people can't (and don't want to) read html-only emails.  After reading it on
the html archives, I'm surprised to see that this would work at all on other
ubuntu versions, and it doesn't look like a bug in our code.  sudo without -i
will look for the .pgpass in the wrong place:

# sudo -u postgres bash -c "echo \$HOME"
/root

# sudo -iu postgres bash -c "echo \$HOME"
/var/lib/postgresql

Do you get a different behavior for those commands on other ubuntu versions?
