GAUSS-00812: "can not set tablespace for partition of neither table nor index"
SQLSTATE: 42601
Description: The tablespace is set for objects other than tables and indexes in a partitioned table.
Solution: Perform this operation on a table or index only.
GAUSS-00816: "cache lookup failed for partition %u"
SQLSTATE: XX000
Description: Failed to find the partition in the cache.
Solution: Ensure that the partition is valid.
GAUSS-00817: "cannot move system relation '%s'"
SQLSTATE: 0A000

Solution: Cancel this operation.
GAUSS-00823: "table '%s' without OIDs cannot inherit from table '%s' with OIDs"
SQLSTATE: 42809
Description: When ALTER TABLE INHERIT is run, tables without OIDs cannot inherit other tables.
Solution: Add OIDs to tables.
GAUSS-00824: "column '%s' in child table must be marked NOT NULL"
SQLSTATE: 42804
Description: When ALTER TABLE INHERIT is run, a parent table has the NOT NULL constraint, but the column of a child table does not have the constraint.
Solution: Add the NOT NUll constraint to the column attribute of the child table.
GAUSS-00825: "child table is missing column '%s'"
SQLSTATE: 42804
Description: When ALTER TABLE INHERIT is run, a child table lacking a column cannot inherit a parent table.
Solution: Add the missing column to the child table, or cancel this operation.
GAUSS-00826: "child table '%s' has different definition for check constraint '%s'"
SQLSTATE: 42804
Description: When ALTER TABLE INHERIT is run, a child table and a parent table have different definitions on a constraint.
Solution: Ensure that the parent and child tables have the same definition on a constraint.
GAUSS-00827: "constraint '%s' conflicts with non-inherited constraint on child table '%s'"
SQLSTATE: 42P17
Description: When ALTER TABLE INHERIT is run, the constraint on a parent table conflicts with the non-inherited constraint on a child table.
Solution: Modify the constraint on the parent or child table.
