How to change the table owner of a Redshift table

Check the current owner of the table using the below query where table_name is the name of your table and schema_name is the name of the schema in lower case.

select tableowner from pg_tables where tablename='table_name' and schemaname='schema_name';

Change the owner of the table using below command where new_owner is the name of the new owner

ALTER TABLE schemaname.tablename OWNER TO new_owner;
commit;                                             

Verify the change by running the select command again.

select tableowner from pg_tables where tablename='table_name' and schemaname='schema_name';
