Hi Greg,
That is what Pierre pointed out, and you are both right. I am using the text mode.
But it seems pretty crazy that a 140meg bit of data goes to 1.3 gigs. Does that seem a bit excessive?
I avoided the binary mode because that seemed to be rather confusing when having to deal with non-bytea data types. The docs make it sound like binary mode should be avoided because what you get back for a datetime varies per platform.
Thanks,
Michael.

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.
