== Functions and Operators
DOC: Enhance SQL Functions documentation Split function section into multiple chapters Add String functions Add (small) section on Conversion/Cast functions Add missing aggregation functions Enable documentation testing (was disabled by accident). While at it, fix failing tests Improve spec tests to allow multi-line queries (useful for docs) Add ability to ignore a spec test (name should end with -Ignore)

SQL: Introduce HISTOGRAM grouping function (#36510) Introduce Histogram grouping function for bucketing/grouping data based on a given range. Both date and numeric histograms are supported using the appropriate range declaration (numbers vs intervals). SELECT HISTOGRAM(number, 50) AS h FROM index GROUP BY h SELECT HISTOGRAM(date, INTERVAL 1 YEAR) AS h FROM index GROUP BY h In addition add multiply operator for Intervals Add docs for intervals and histogram Fix #36509
