Probably but it's also a pretty technical point and you're programming
in C so it's kind of borderline.
If you're using text-mode then your datum that you're getting from
libpq is a text representation of the datum. For bytea in released
versions that means anything which isn't a printable ascii character
will be octal encoded like \123. You can use PQunescapeBytea to
unescape it.
If you use binary encoding then you don't have to deal with that.
Though I seem to recall there is still a gotcha you have to worry
about if there are nul bytes in your datum. I don't recall exactly
what that meant you had to do though.
