DATE_BIN - bins timestamps into intervals (PostgreSQL 14+).

Rounds a timestamp down to the nearest multiple of stride from origin. Useful for time-series bucketing.

Example

use drizzle_core::expr::date_bin;

// SELECT DATE_BIN('15 minutes', events.created_at, TIMESTAMP '2001-01-01')
let bucketed = date_bin("15 minutes", events.created_at, "2001-01-01");
