Hi, I'm not sure whether it is OK, a blank format for bytea, which is presented in 9.1devel (pg_dump and psql)
Earlier versions (7, 8): psql - signature bytea not null default '':: bytea pg_dump - signature bytea default ''::bytea not null postgresql.conf: standard_conforming_strings = off bytea_output = 'hex' 9.1devel: psql - signature bytea not null default '\ x':: bytea pg_dump - signature bytea default '\\x'::bytea not null Best regards Vladimir Kokovic, DP senior, Belgrade, Serbia
