I maybe be missing it, but I see no LIMIT in the function.
I do see OFFSET and it looks backwards to me?:

LIMIT Clause
The LIMIT clause consists of two independent sub-clauses:
LIMIT { count | ALL }
OFFSET start
Also I not sure what offset_num is supposed to do, it is declared
but not used?
Yep.. it's declared but it's not used..
Hmm.. interesting that about the LIMIT clause
However.. I had to changed the function...
Here is the new one:
CREATE or REPLACE FUNCTION function_data_1(rows integer)
RETURNS INTEGER AS $$
declare
completed integer;
offset_num integer;
crtRow record;
BEGIN
offset_num = 0;
INSERT INTO table2_y_b (note_id, size, file_id, full_path)
(
SELECT
t1.note_id,
t1.size,
t1.file_id,
t1.full_path
FROM
table1_n_b t1
JOIN
table3_n_b t3 ON t3.file_id = t1.file_id
);
UPDATE table2_y_b t2 SET segment_data =
(
SELECT
o1.data
FROM
original_table1_b o1
JOIN
table3_n_b t3 ON t3.file_id = o1.file_id
WHERE
t2.migrated = 0
AND
t2.file_id = o1.file_id
);
UPDATE table2_y_b SET migrated = 1 WHERE file_id =
crtRow.file_id AND migrated = 0;
UPDATE original_table1_b SET data = NULL WHERE file_id =
crtRow.file_id;
END
$$ language 'plpgsql';
It's all working, except the LIMIT... if possible can you please give
me an example of that LIMIT in some of those queries?
I do not what you are trying to LIMIT/OFFSET, so I have no idea where to
place the LIMIT/OFFSET.
Maybe an example query showing what you are trying to do will help?
Thanks
