Hi.
I've still got something I can't seem to get. In my test cases with simple
tables the first uint16 of tuple data after the header contained the length
of the tuple. In this case I can't seem to figure out what the value F24D
stands for when I'd expect it's length to be 0800.
The first tuple in my table has:
OID: 6155665
t_cmin: 32494973
t_cmax: 0
t_xmin: 32494324
t_xmax: 32495742
t_ctid: 55181312:82
t_infomask: A503
Bitmap: 3F00000000F2
Attributes: 7
Data Offset: 36
The flags for this tuple say:
HEAP_MOVED_IN
HEAP_UPDATED
HEAP_XMAX_COMMITTED
HEAP_XMIN_INVALID
HEAP_HASVARLENA
HEAP_HASNULL
Tuple Data:
F24D 0000 FFFF FFFF 1300 0000 4E65 7720 4D61 696C 2046 6F6C 6465 7200
9F00 0000 9F00 0000 48A2 1800
The schema is: Attribute | Type | Modifier
-------------+-------------+------------------------------------------------
--------userid | integer | not nullfolderid | integer | not null default
nextval('folders_folderid_seq'::text)foldername | varchar(25) |messages | integer |newmessages | integer
|foldersize | integer |popinfo | integer |
Indices: folder_folderid_idx, folders_pkey
thanks
