Function hasMultipleStatements

backend/api/v1/sql_service.go:503–515

hasMultipleStatements reports whether a batch has more than one non-empty statement. Multi-statement batches can change the session's default schema mid-batch (e.g. Postgres `SET search_path`), so DML/DDL in them falls back to the database-level check. SUP-222.
