It's not supposed to. I was able to reproduce this in 7.4 by arranging
for the client disconnect to occur at just the right time (it has to
happen *after* the 'invalid string enlargement' message is sent to the
client, but *before* the 'not in in-progress' message gets sent, so that
that latter message is the first one to get a send failure).
I cannot duplicate the problem in 8.0 but I'm unconvinced that it
couldn't happen. I think what we should do about it is rejigger
errstart() so that COMMERROR isn't promoted up to ERROR just because
it happens during error recovery. Really the notion of promoting
errors is wrongheaded to start with --- if it's a below-ERROR case
then we should just print it and return.
