    Please use the following query.

    => SELECT
    ->   node_name,
    ->   count(CASE WHEN request_type ='LOAD' THEN 1 ELSE null END) AS loads_initiated,
    ->   count(CASE WHEN request_type ='QUERY' THEN 1 ELSE null END) AS selects_initiated
    -> FROM
    ->   dc_requests_issued
    -> GROUP BY node_name
    -> ORDER BY node_name;
    
        node_name  | loads_initiated | selects_initiated
    ---------------+-----------------+-------------------
     v_db_node0001 |             475 |              1182
     v_db_node0002 |               0 |               890
