Forum OpenACS Q&A: Response to Postgres 7.1 beta 1 problems

You should submit an example of a failing view with outer join to the
Postgres developers, so they can fix it before the beta release if
possible.  It may not be, as this release doesn't include the
from-the-ground-up redesign of the query tree (i.e. parser/semantic
analyzer output) that's planned for 7.2, and some complex queries just
won't map to the current internal representation.
