20. def resolverExpression(queryString: String, errorMessage: String, bindVars: List[String]): String

    Returns resolver expression string - db function call to check resolver result and throw exception when result is not unique or is missing.

    Returns resolver expression string - db function call to check resolver result and throw exception when result is not unique or is missing. This is important to avoid silent deletion of data from db. Default implementation is

    s"checked_resolve(_, array($queryString), $errorMessage)"

    For postgresql bigint and string resolvers checked_resolve db function can be defined as:

    create or replace function checked_resolve(resolvable text, resolved bigint[], error_message text)
      returns bigint as $$
    begin
      if array_length(resolved, 1) > 1 or resolvable is not null and resolved[1] is null then
        raise exception sqlstate '235BX' using message = error_message;
      else
        return resolved[1];
      end if;
    end;
    $$ language plpgsql immutable;
    
    create or replace function checked_resolve(resolvable text, resolved text[], error_message text)
