You should probably make sure the PG hackers list is aware that outer joins aren't working within a view. Outer joins are new and views have been rewritten, and this is pre-beta software - perfect timing for a bug report.
As for the delete problem, I'm still stumped. Since thousands of PG users can delete rows from their tables with no error, I'm certain it's some sort of "cockpit error", i.e. something you've done. For the life of me, though, nothing comes to mind.
