**Table 1** PG_INHERITS columns
Name	Type	Reference	Description
inhrelid	oid	PG_CLASS.oid	OID of the child table
inhparent	oid	PG_CLASS.oid	OID of the parent table
inhseqno	integer	-	If there is more than one direct parent for a child table (multiple inheritances), this number tells the order in which the inherited columns are to be arranged. The count starts at 1.
