using distinct in query causes steampipe to hang

[dboeke]

Describe the bug Not sure if this is a plugin issue or steampipe issue, but when I add the distinct keyword to my query, steampipe goes into an endless loop that I can't break with ctrl-c (needed to use ctrl-z) and then force quit the steampipe service.

Steampipe version (steampipe -v) Example: v0.3.6

To reproduce

select distinct
  group_id,
  cidr_ip
from
  aws_vpc_security_group_rule;

Expected behavior Query returns a value or error message.

Additional context Add any other context about the problem here.
