Description:
Hi,
From the documentation [0] about the encode function, the "escape" format
should "convert zero bytes and high-bit-set bytes to octal sequences (\nnn)
and doubles backslashes."
However, executing "select encode(E'aaa\bccc', 'escape');" outputs
"aaa\x08ccc", although according to the documentation I should get
"aaa\010ccc". This was found in [1] while mimicking the output of encode,
where you can get more details.
Cheers,
