Hello,
Does anyone know what the format of hex characters for postgres are?   
I'm trying to create files that contain a 0x55.  It looks to me like  
it should require a delimiter of some sort between the characters.  I  
don't know how postgres would know that the string was a hex  
representation and not just a character zero, followed by a character  
x, followed by a character 5, followed by a character 5.
