Hi I've just compiled the 9.0 beta1 source tarball and am testing my custom application against it (which has been running on PostgreSQL since 7.3 or so).
The below statement results in the following error message: "ERROR: btree index keys must be ordered by attribute" evidently in relation to the subselect. The statement works fine on previous versions up to 8.4.3. I can provide more details later if required: SELECT o.object_id FROM object o INNER JOIN class c ON (o.class_id = c.class_id) INNER JOIN object_version ov ON (o.object_id = ov.object_id) INNER JOIN site ON (o.site_id=site.site_id) WHERE o.object_id = '3143' AND ov.version = '0' AND o.site_id = '2' AND ov.object_status_id = (SELECT MAX(ov1.object_status_id) FROM object_version ov1 WHERE o.object_id=ov1.object_id AND ov1.version = ov.version AND ov1.lang = ov.lang ) AND ov.lang = 'en' SELECT version(): PostgreSQL 9.0beta1 on i686-pc-linux-gnu, compiled by GCC gcc (Ubuntu 4.3.2-1ubuntu12) 4.3.2, 32-bit Ubuntu 8.10 running on a "VIA C7-M" Processor (netbook).
