I have not dug into your function deep enough to understand all the
relationships
involved so I cannot offer anything specific. A generic method:
test[5432]=# create table ts_stamp_test(id serial PRIMARY KEY, uid integer,
stamp integer NOT NULL);
CREATE TABLE
test[5432]=# insert into ts_stamp_test (uid, stamp) values (1, 5), (2, 10), (1,
12), (2, 15), (1, 18), (2, 30);
INSERT 0 6
test[5432]=# select * from ts_stamp_test;
id | uid | stamp
----+-----+-------
1 | 1 | 5
2 | 2 | 10
3 | 1 | 12
4 | 2 | 15
5 | 1 | 18
6 | 2 | 30
(6 rows)
test[5432]=# select * from ts_stamp_test where uid = 1 order by stamp desc
limit 1;
id | uid | stamp
----+-----+-------
5 | 1 | 18
(1 row)
