Problem Summary: Create two tables, t1 and t2. Create a primary key on table t1 and a foreign key on table t2 referencing t1 primary key. Then drop table t2, and then try to delete the primary key on t1. doris will report error: errCode = 2, detailMessage = Can not find table XXXX in constraint. This is because the `foreignTables` metadata in the `PrimaryKeyConstraint` was not updated when the foreign key table was dropped. `foreignTables` stores the table IDs of the foreign key tables that reference the primary key. When dropping the foreign key table or drop the foreign key, the corresponding entries in `foreignTables` should also be removed.
