I reproduced it more simply than the 300 line script:
postgres=# CREATE TABLE t(i int)PARTITION BY RANGE(i);
postgres=# CREATE TABLE t1 PARTITION OF t FOR VALUES FROM (1) TO (9);
postgres=# INSERT INTO t1 VALUES(1),(2);
postgres=# ANALYZE VERBOSE t;
postgres=# SELECT * FROM pg_stat_user_tables WHERE relname='t';
(0 rows)
postgres=# SELECT 1 FROM pg_statistic WHERE starelid='t'::regclass;
?column? | 1
