The above says the data was inserted.
But not into the MV but into TASK_DEPENDENCY⠒V.
Where and when was the count query run?
Excerpt of the according protocol:
## tenth level ##
Set materialised view QUERY_PER_TASK⠒MV up
psql:views/QUERY_PER_TASK⠒MV.pg_sql:3: HINWEIS: materialisierte Sicht
»query_per_task⠒mv« existiert nicht, wird übersprungen
DROP MATERIALIZED VIEW
SELECT 0
REFRESH MATERIALIZED VIEW

At above you have not entered the data into the tables the MV depends on
so SELECT 0 is reasonable.

The 0 count above represents the below correct? :
select count(*) from SNOWRUNNER.QUERY_PER_TASK⠒MV;
If so, again that is reasonable as I don't see anywhere you refresh
QUERY_PER_TASK⠒MV after the underlying tables have data entered. At this
point it is still at the state you left it at here:
## tenth level ##
Set materialised view QUERY_PER_TASK⠒MV up
psql:views/QUERY_PER_TASK⠒MV.pg_sql:3: HINWEIS: materialisierte Sicht
