Broken range + interval + preceding in PostgreSQL

[alippai]

The following breaks the PRECEDING in sqlglot 14.1.1, but PostgreSQL accepts it:

select LAST_value(col1) OVER(ORDER BY col2 RANGE between interval '1 day' PRECEDING  AND '10 days' FOLLOWING) FROM tbl

Note the interval keyword. I didn't find it in the docs (other than it's the INTERVAL type used if col2 is DATE type), but it works and creates the same query plan with our without the additional interval.
