already treating it as text anyway, to the point that I couldn't find anything to change except the datatype markings in catalog/*.h. The only effect that the bytea declaration had was to cause byteaout() to be invoked when pg_dump (or another client program) inspected the column value. Since pg_dump wasn't expecting that, but just treating what it got as text, the net result is that dump and reload would mangle any backslashes or non-ASCII characters in the filename string for a C-language function. That is a very long-standing bug, but given the lack of field complaints it doesn't seem worth trying to find a back-patchable fix. We'll just make this change to fix it going forward. This change will also forestall problems after the planned change to let bytea emit hex output instead of escaped characters.
