  • this is merely building on top of already existing "connect by" functionality for snowflake :)
  • and making the start with clause optional as per docs and encountered in the wild
  • the AST doesn't expose, however, the information which form was parse, i.e. either START WITH .. CONNECT BY .. or the other way around

i can't verify this change for snowflake, but this doc indicates to me that it's ok
