They're not supposed to be. PQescapeBytea creates something that can be
inserted into a SQL command as a string literal. PQunescapeBytea
deconstructs something that has been returned as a SELECT result.
There are two different levels of backslashing involved.
This doesn't directly answer your original problem, but I think we'll
need to see more of your code to figure out what you were doing wrong.
