Doesn't it tell you? AFAICS every PG version that uses that error
message phrasing gives you the exact byte sequence it's complaining
about.
It would also be worth asking what PG version you are using anyway.
If it's not a pretty recent update then updating might help --- I
think there were some bugs in the encoding verification stuff awhile
back.
