I have tried to pg_dump only one single table with bytea field and the
result is the same when I come to restore with mysql.

Hi George,
This is my guess to the cause of the problem (I could be wrong).

You edited the pg_dump generated sql file to suit to suit the requirements
of your target server (MySQL), during this edition, your editor may have
inserted line terminators where it found long sentences, this long sentences
may have been the contents of your bytea column(s) thereby changing the data
of the bytea column(s).

Allan.
