Thanks for an answer and for moving it to the proper mailing list.
There were a few issues with postgres 9 that were fixed in changeset 5074,
what revision is your galaxy instance running?
I am still running the stable version (galaxy-dist branch). I guess that with this version I need to stick with the older postgres 8.x. And I will try now, separately, to use the development version (galaxy-central branch).
If you are running something newer than that, could you explain more explicitly the steps to reproduce the server error?
Even though perhaps there is no need to investigate further - all I need is to use the fixes introduced in 5074 - but still I am attaching the error I got. Mainly because it is only my guess that the error was caused by the new postgres (because it does not occur when I switch back to sqlite).
Thanks, Martin
