Grant permissions on future tables

The following code block grants future permission to the role snowboard_role on all future tables and views in a database. This is needed for older Snowflake installations that only support future grants on the schema level.
EXECUTE IMMEDIATE $$
-- TODO CHANGE database_name
DECLARE
database_name TEXT := 'EXAMPLE_DB';
log_text TEXT;
grant_statement TEXT;
schema_name TEXT;
res_schemas RESULTSET;
res resultset;
BEGIN
log_text := 'START - ';
grant_statement := 'show schemas in database ' || :database_name;
res_schemas := (EXECUTE IMMEDIATE :grant_statement);
FOR record IN res_schemas DO
IF (record."name" != 'INFORMATION_SCHEMA') THEN
schema_name := :database_name || '.' || record."name";
grant_statement := 'grant select, references on future tables in schema ' || schema_name || ' to role snowboard_role; ';
res := (EXECUTE IMMEDIATE :grant_statement);
grant_statement := 'grant select, references on future views in schema ' || schema_name || ' to role snowboard_role; ';
res := (EXECUTE IMMEDIATE :grant_statement);
log_text := log_text || record."name" || ' GRANTED - ';
END IF;
END FOR;
RETURN log_text;
END;
