Error "call is missing required quals" should include table name

[e-gineer]

When I use multiple tables in a join, the "call is missing required quals" error should specify which table the error applies to so the user can determine the actual cause of the error.

For example ... which table is failing here?

> select
  *
from
  fastly_service_version as v,
  fastly_acl as acl,
  fastly_acl_entry as e
where
  acl.service_id = v.service_id
  and acl.service_version = v.number
  and e.service_id = v.service_id
  and e.acl_id = acl.id
Error: rpc error: code = Internal desc = 'List' call is missing required quals: 
column:'service_id' operator: =
column:'service_version' operator: =
