Not 100% complete support, but solves major blockers using Redshift:

  1. Prevents DISTINCT ON being used for group ... take 1 deduplication.
  2. Escape keywords when used as column names.

let ident = ident.to_ascii_uppercase();

sql_keywords().contains(ident.as_str())
sql_keywords().contains(ident.as_str()) || dialect_keywords(dialect).contains(ident.as_str())

I'm a bit unsure about this but does not seem to have any side-effects and opens the capability to selectively escape keywords when used as column names.
