I used a slight modification of the case mentioned on the docs. I
confirm this fails repeatably for me on current HEAD.
CREATE TABLE cities (
city_id bigserial not null,
name text not null,
population bigint
) PARTITION BY LIST (left(lower(name), 1));
CREATE TABLE cities_ab
PARTITION OF cities (
CONSTRAINT city_id_nonzero CHECK (city_id != 0)
) FOR VALUES IN ('a', 'b')
PARTITION BY RANGE (population);
drop table cities;
ERROR: cannot drop table cities because other objects depend on it
DETAIL: table cities_ab depends on table cities
HINT: Use DROP ... CASCADE to drop the dependent objects too.
I notice also that
\d+ <tablename>
does not show which partitions have subpartitions.
I'm worried that these things illustrate something about the catalog
representation that we may need to improve, but I don't have anything
concrete to say on that at present.
