[apologies -- this amounts to a cross-post on subject "DB with bytea types reload problem" -- I'm fairly desperate!] Hi Jonathan I saved a db with some bytea columns to text using pg_dump -a -d <db> > out.sql If I go psql: \i out.sql multiple errors result, such as: psql:out.sql:505: invalid command \N psql:out.sql:505: invalid command \ The sql dump file has lines starting something like this for the photo table: 1 500 375 h \\377\\330\\377\\340\\000\\020JFIF\\000\\001\\001\\001\\000H\\000H\\000\\000\\377\\341\\023>Exif\\000\\000MM\\000*\\000\\000\\000\\010\\000\\012\\00.... Is there any way I can retrieve the image data?
