If t_len were *less* than that, it would be a bug. But I think it's
fairly common for t_len to be rounded up to the next maxalign boundary.

You mean even if relacl is not null? Sounds improbable: AFAIR, pg_class
tuples are built with heap_form_tuple, same as anything else.

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 before
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
