Hm, and RowDescription ('T') messages are also not being printed ... so
I think there's some larger problem here, and perhaps it needs to be
fixed using a different approach.
After staring at it a couple of times, I think that the places in
pqParseInput3() where there's a comment "... moves inStart itself" and
then "continue;" should have a call to pqTraceOutputMsg(), since AFAIU
those are the places where the message in question would not reach the
"Successfully consumed this message" block that prints each message.

Maybe there's lots of data loss but the records of data loss are also lost.
