Quoting Bruce Momjian (maillist@candle.pha.pa.us): > I assume you are asking of attlen for char() and varchar() have the max > length. The answer is now NO. They are varlena structures like text, > and so have a attlen of -1. Atttypmod for that pg_attribute row now has > the defined length. > Even for a char(4) field? ok, if attlen doesn't give the length of a field, how do I find it? Right now: yes, but I would like to see the char() type changed to a fixed length type (which it really is) then it would have the length in attlen. Right now the length for char and varchar is in atttypmod. Andreas
