It's actually UTF-8 text, and some PostgreSQL functions are only
available for TEXT, but not BYTEA, e.g.:
bfk_int=> SELECT '\x006500'::bytea ~ 'A';
ERROR: operator does not exist: bytea ~ unknown
LINE 1: SELECT '\x006500'::bytea ~ 'A'; ^
HINT: No operator matches the given name and argument type(s). You might need to add explicit type casts.
