Please reply to the list, not to me.  Unfortunately the list doesn't set 
reply-to.

Please provide the FULL EXACT TEXT OF THE ERROR MESSAGE by copying and 
pasting it into an email.

See: http://wiki.postgresql.org/wiki/Guide_to_reporting_problems


As for byte array differences, which client library are you using? Is it 
possible it's outdated and doesn't understand bytea_format=hex ?  See 
http://www.postgresql.org/docs/9.1/static/datatype-binary.html .
