I tried the following query and it crashed the backend. (CVS of a couple
of days ago).
SELECT category.oid, category.title, category.image FROM story,
category* WHERE story.category = category.oid AND story.approved GROUP
BY category.oid, category.title, category.image ORDER BY min(datetime);
pqReadData() -- backend closed the channel unexpectedly. This probably means the backend terminated abnormally
before or while processing the request.
We have lost the connection to the backend, so further processing is
impossible. Terminating.
