Are multiple identical entires in pg_depend possible?
If so, how do they occur, and what is the purpose of representing
exactly the same dependency two times in pg_depend?
I expected the following query not to return any rows, but it did:
glue=# select count(*), * from pg_depend group by classid, objid,
objsubid, refclassid, refobjid, refobjsubid, deptype having count(*) >
1;count | classid | objid | objsubid | refclassid | refobjid |
refobjsubid | deptype
-------+---------+-------+----------+------------+----------+-------------+--------- 2 | 2618 | 11015 | 0
| 1259 | 11012 | 1 | n
(1 row)
