I have a master table called fact_sgw and have a child table called fact_sgw_2016_06 which is just data for June 2016. Could I truncate the child table without losing any data from the master table (fact_sgw)?
TRUNCATE ONLY childtablename
TRUNCATE TABLE <child_table_name> works fine on Postgres 14.
TRUNCATE TABLE <child_table_name>
