Environment:PHP 5.2.6, PostgreSQL 8.3.10
I get the following error when accessing the board-wide feed (myboard.example/feed.php).
General Error SQL ERROR [ postgres ] ERROR: invalid reference to FROM-clause entry for table "p" LINE 1: ...users u LEFT JOIN phpbb_forums f ON (f.forum_id = p.forum_id... ^ HINT: There is an entry for table "p", but it cannot be referenced from this part of the query.

I tested release 3.0.7 and the current trunk, both with MySQL and PostgreSQL. The bug appears only with PostgreSQL, but that is probably only because MySQL's relaxed restrictions on SQL queries. I have examined the query that causes the error and I think that the order of tables in the FROM clause is wrong (see e.g. http://archives.postgresql.org/pgsql-general/2006-09/msg01041.php).
To fix the bug, it is enough to change the order of tables (patch against the current trunk is attached).
