SUMMARIZEsupport for named tables and query inputs such asSELECT,FROM,VALUES, parenthesized queries, and CTEs.The syntax is represented as a query AST node so it can also be used in subqueries, for example
SELECT column_name FROM (SUMMARIZE SELECT 42 AS answer).Reference: https://duckdb.org/docs/stable/guides/meta/summarize.html
