[BUG] Don`t cascade drop tables.

[XBsleepy]

I am trying this interesting repo:
I create a partition table ,and use measurement.

CREATE TABLE measurement(
city_id int not null,
logdate date not null,
peaktemp int,
unitsales int
)partition by range(logdate);
select enable_ts_table('measurement');

Then I try to drop it (both cascade and no cascade have been tested):

DROP TABLE measurement CASCADE;

Then I create the same partition table, try to use ts_table, it doesn't work:

NOTICE:  relation "template_public_measurement" already exists, skipping
ERROR:  duplicate key value violates unique constraint "part_config_parent_table_pkey"

We have to delete it manually.

DELETE FROM part_config where part_config.parent_table ='public.measurement';
