Description:

Greetings,

I do not know the severity of this bug. I stumbled up due to a typo ( `a`
instead of `ag`).
In a series of multiple INNER JOINS, I referenced wrongly another table and
the postgres docker container bloated a 64GB RAM.
The commented out line is the fix.
I could submit more details.

Regards,
Dimitris

```
CREATE OR REPLACE VIEW exampledb.vw_project_summary AS
SELECT
p.project_id
, p.project_name
, ag.unique_values AS implementing_agencies
FROM exampledb.mt_project p
INNER JOIN exampledb.vw_action_types_per_project a
ON (p.project_id = a.project_id)
INNER JOIN exampledb.vw_agencies_per_project ag
ON (p.project_id = a.project_id);
-- ON (p.project_id = ag.project_id);

```
