Avoid dropping Postgres schema
The postgres user needs to be an owner of the public schema or a superuser in order to execute the schema.sql for database initialization. To avoid that, two changes are required: - use `CREATE TABLE IF NOT EXISTS` in order to idempotently create the necessary tables - handle conflicts when inserting duplicate data This follows the pattern in use by the src/main/resources/db/mysql/{data,schema.sql} files.
