Looking at how byteain detects whether the input it is passed is the new
hex format escape or the old octal escape, it uses:
char *inputText = PG_GETARG_CSTRING(0);
if (inputText[0] == '\\' && inputText[1] == 'x')
Doesn't this read off the end of inputText in the case of "SELECT
''::bytea", or is there some padding happening somewhere that makes this
legal?
