0x45 = 'E' would be an error message. If you look in the postmaster
log file you should see the error being logged. My guess is that the
backend is crashing, and is managing to output an error message just
before it goes down; but libpq isn't expecting any error message and
fails to cope.
There's not enough info here to figure out why the backend is crashing.
The error message might help...
