The catalog pg_inherits records information about
- table inheritance hierarchies. There is one entry for each direct

+ table and index inheritance hierarchies. There is one entry for each direct
+ parent-child table or index relationship in the database. (Indirect
+ inheritance can be determined by following chains of entries.)
oid
pg_class.oid
- The OID of the child table
+ The OID of the child table or index
oid
pg_class.oid
- The OID of the parent table
+ The OID of the parent table or index
If there is more than one direct parent for a child table (multiple
inheritance), this number tells the order in which the
inherited columns are to be arranged. The count starts at 1.
+ Indexes can not have multiple inheritance, since they can only inherit
+ when using declarative partitioning.
