Ok, I upgraded my CVS sources yesterday, and simple inherited/GROUP BY
queries are working again. But a more complex one still seems broken.
This is the query...
httpd=> SELECT question.oid, question.title, question.summary,
question.datetime, category.oid, category.title, category.image, email,
webuser.name, count(comment.oid) FROM question, webuser,
category*,comment WHERE question.webuser = webuser.oid and
question.category = category.oid AND comment.webobject = question.oid
GROUP BY question.oid, question.title, question.summary,
question.datetime, category.oid, category.title, category.image, email,
webuser.name UNION SELECT question.oid, question.title,
question.summary, question.datetime, category.oid, category.title,
category.image, webuser.email, webuser.name, 0 FROM question, webuser,
category* WHERE question.webuser = webuser.oid and question.category =
category.oid;
ERROR: replace_vars_with_subplan_refs: variable not in target list
