CREATE TABLE t (dt DATE) PARTITION BY RANGE COLUMNS(dt) (PARTITION p0 VALUES LESS THAN ('not-a-date'));expected output

Use type-compatible values in COLUMNS partitioning
CREATE TABLE t (dt DATE) PARTITION BY RANGE COLUMNS(dt) (PARTITION p0 VALUES LESS THAN ('2024-01-01'), PARTITION p1 VALUES LESS THAN (MAXVALUE));Why this works
Date literals in YYYY-MM-DD format are type-compatible with DATE columns.
