"hash" column name is not escaped in Big Query

[mihkelambre]

What happened?

Cannot select a column named 'hash' because BigQuery recognizes 'hash' as a function. PRQL does not escape the column name (by adding backticks) nor does it preserve existing backticks, as shown in the example below.

PRQL input

prql target:sql.bigquery

from `some_dataset_id.demo`
select {
  `hash`
}

SQL output

SELECT
  hash
FROM
  `some_dataset_id.demo`

-- Generated by PRQL compiler version:0.13.3 (https://prql-lang.org)

Expected SQL output

SELECT
  `hash`
FROM
  `some_dataset_id.demo`
