8 bytes is certainly not the right answer.

Creating a little table, and throwing some wide strings at it...

tutorial=# create table widetext (main text);
CREATE
tutorial=# insert into widetext values ('0123456789... repeated a
bunch of times...');
INSERT 2625519 1
... increasing size each time, for several instances ...

tutorial=# select length(main) from widetext;length 
--------  1100  5500 11000
(3 rows)

That's way more than 8 bytes; that's way more than 5000 bytes.

What tool are you using to insert the data?

Is it possible that it has some buffer size limitation that is biting
you?
