If you're trying to write a bytea[] literal, I think the most reliable
way to write the individual bytes is
\\\\nnn
where nnn is *octal*. The idea here is:
* string literal parser takes off one level of backslashing,
leaving \\nnn
* array input parser takes off another level, leaving \nnn
* bytea input parser knows about backslashed octal values
Note it has to be 3 octal digits every time, no abbreviations.
