It was chosen to FORCE, not AVOID, crossing dst.

cdrs=# select x, '2019.11.20 20:00:00'::timestamptz + x::interval as
sum from ( values ('0'),('5 mons 10 days 10:00:00'),('163 days
11:00:00'),('3923:00:00')) as v(x);
x | sum
-------------------------+------------------------
0 | 2019-11-20 20:00:00+01
5 mons 10 days 10:00:00 | 2020-05-01 06:00:00+02
163 days 11:00:00 | 2020-05-02 07:00:00+02
3923:00:00 | 2020-05-02 08:00:00+02

Subject is just complex enough I should avoid making this typos!
Apologies, my fault, bad proof reading, hungry....
