Dead code?

Is there anywhere we make use of this code that handles attlen == -2?

If so I'm curious where because I was thinking of doing something similar and
didn't realise we already had this capability. But I suspect it's just dead
code left over, possibly from the days before the Name data type?


/** att_addlength increments the given offset by the length of the attribute.* attval is only accessed if we are
dealingwith a variable-length attribute.*/
 
#define att_addlength(cur_offset, attlen, attval) \
( \((attlen) > 0) ? \( \    (cur_offset) + (attlen) \) \: (((attlen) == -1) ? \( \    (cur_offset) +
VARATT_SIZE(DatumGetPointer(attval))\) \: \( \    AssertMacro((attlen) == -2), \    (cur_offset) +
(strlen(DatumGetCString(attval))+ 1) \)) \
 
)
