+-- Drop all TPC-H Primary Key and Unique Key Constraints
+alter table region drop r_pk;

Review Comment:
   This cleanup script needs to use the constraint-drop form, e.g. `alter table 
region drop constraint r_pk;`, for all of these entries. Doris' constraint 
grammar only maps `ALTER TABLE ... DROP CONSTRAINT <name>` to 
`DropConstraintCommand` (`DorisParser.g4` has `DROP CONSTRAINT 
constraintName`), and the FK cleanup script in this PR already uses that form. 
As written, running this file will not remove the PK/UK constraints that 
`tpch-fd.sql` adds, leaving the metadata in place for later plans.
