Table 52.27. pg_inherits Columns

Name Type References Description

Name	Type	References	Description
`inhrelid`	`oid`	`pg_class.oid`	The OID of the child table or index
`inhparent`	`oid`	`pg_class.oid`	The OID of the parent table or index
`inhseqno`	`int4`		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.
