Sorry, I got distracted by another project of mine and real life issue.

So I'm not sure about why there is only a single backslash for bytea values as 
string litteral but two backslashes are clearly necessary. Indeed, the two 
backslashes are first interpreted by the string litteral parser which leads to 
a single escape in the result, something of the form '\x...'. Then this is 
parsed by the bytea input which transform it into a sequence of bytes.

Adrien, are you familiar with gdb? If yes, would you mind helping me debug 
this issue? We could set up a meeting on IRC which would be the most 
convenient way to do it or do it over email (that would be a bit slower but 
allow for more asynchronism between us).

Best regards,

Thomas
