get_substrait does not support DELIM_JOIN

[EpsilonPrime]

The substrait integration is experimental. Support is currently only available on request.

• I have permission to ask for support.

What happens?

If you pass TPC-H query 2 to get_substrait() it complains that DELIM_JOIN Is not supported.

To Reproduce

install substrait;
load substrait;
install tpch;
load tpch;

.width -1
.mode csv
select query from tpch_queries() where query_nr=2;

FROM get_substrait("SELECT
      s_acctbal,
      s_name,
      n_name,
      p_partkey,
      p_mfgr,
      s_address,
      s_phone,
      s_comment
  FROM
      part,
      supplier,
      partsupp,
      nation,
      region
  WHERE
      p_partkey = ps_partkey
      AND s_suppkey = ps_suppkey
      AND p_size = 15
      AND p_type LIKE '%BRASS'
      AND s_nationkey = n_nationkey
      AND n_regionkey = r_regionkey
      AND r_name = 'EUROPE'
      AND ps_supplycost = (
          SELECT
              min(ps_supplycost)
          FROM
              partsupp,
              supplier,
              nation,
              region
          WHERE
              p_partkey = ps_partkey
              AND s_suppkey = ps_suppkey
              AND s_nationkey = n_nationkey
              AND n_regionkey = r_regionkey
              AND r_name = 'EUROPE')
  ORDER BY
      s_acctbal DESC,
      n_name,
      s_name,
      p_partkey
  LIMIT 100;
  "
  );

The result is:
