Need exact SQL query to find List of Detach Partitioned Tables (Yet to
be Dropped)
The following is the query which i used, i am using and i found an bug
which is listing an newly created table (last week)
As David G. Johnston said how would you know it was formally a partition?:
https://www.postgresql.org/docs/current/sql-altertable.html
"
DETACH PARTITION partition_name [ CONCURRENTLY | FINALIZE ]
This form detaches the specified partition of the target table. The
detached partition continues to exist as a standalone table, but no
longer has any ties to the table from which it was detached.

The only I could see this working is if you had a standard naming scheme
for partitions and then you could do a regex search in pg_class for that
pattern where relkind = 'r'.
SELECT relnamespace::regnamespace::text AS schema_name, relname AS
table_name
FROM pg_class c
WHERE NOT relispartition -- !
AND relkind = 'r' and lower(relnamespace::regnamespace::text) not in
('pg_catalog','partman','information_schema') and
lower(relnamespace::regnamespace::text) in ('XYZ')
order by relnamespace::regnamespace::text, relname ;
