Here's what you're seeing:
0\332\000\011\00
5c is a backslash, the rest are all digits. The backslashes introduce
octal escape codes - that's what bytea_output = 'escape' means. 0332
is 0xda, 011 is 0x09, etc. You're seeing the same values come up in
the cases where they don't need to be escaped, like the 0x30 at the
beginning.
