I am sorry. It was a bug in my code. I did not add the size of the tuple's
header field to the off variable

Hello,
Can the t_len field in HeapTuple structure be used to verify the length of
the tuple?
That is, if I calculate the length from the contents of the tuple using
data from pg_attribute for fixed length fields and the data from the header
for varlena fields, should it always match the value sto
