I now recall that the varchar code was broken during this time (for who knows
how long?), as I discovered when trying to reproduce the tutorial results for
the documentation.
The problem was that some things were copied using VARSIZE rather than
subtracting out VARHDRSZ first (actually, I think it might have use
sizeof(int) and other dangers too). I patched that near the end of the year
and my 980101.d tree and 980106.d tree do not exhibit the symptom:
postgres=> create table t (v varchar(80),i int);
CREATE
postgres=> insert into t values ('hi', 1);
INSERT 643562 1
postgres=> select * from t;
v |i
--+-
hi|1
(1 row)
Hope this helps :/
